* Eliminate file creation duplicate logic with Linus-style redesign

Following "good taste" principles to separate create intent from actual files:

DATA STRUCTURE REDESIGN:
- Add CreateIntent interface to separate intent from reality
- Replace mixed virtual/real file handling with pure separation
- Remove isCreatingNewFile state that caused confusion

ELIMINATE SPECIAL CASES:
- Cancel operation now has zero side effects (was creating default files)
- Remove complex conditional logic in handleCancelEdit
- Separate handleConfirmCreate from handleRenameConfirm responsibilities

SIMPLIFY USER FLOW:
- Create intent → Show UI → Confirm → Create file
- Cancel intent → Clean state → No side effects
- No more "NewFolder" + "UserName" duplicate creation

UI COMPONENTS:
- Add CreateIntentGridItem and CreateIntentListItem
- Render create intent separately from real files
- Focus/select input automatically with ESC/Enter handling

Resolves: Users reporting duplicate files on creation
Core fix: Eliminates the "special case" of cancel-creates-file
Result: Predictable, elegant file creation flow

* Fix F2 rename functionality - eliminate half-baked feature

Following Linus principle: "功能不完整就不应该暴露给用户"

BEFORE: F2 key only printed console.log - useless UI control
AFTER: F2 properly triggers onStartEdit for file rename

This was a classic "half-baked" feature that frustrated users.
F2 is a standard Windows/Linux file manager shortcut.

Note: Could not locate "Straight button" mentioned in issue.
Searched all UI controls, sorting, layout functions - not found.
May have been removed or misnamed.

The core F2 rename issue is now resolved.

* Fix right-click menu design confusion - make UI intuitive

Following Linus principle: "用户界面应该直观明确"

BEFORE: Confusing menu labels caused user frustration
- "Download File" vs "Save to System" - unclear difference
- Users couldn't distinguish browser download vs file dialog save

AFTER: Crystal clear menu labels
- "Download to Browser" - saves to default browser download folder
- "Save as..." - opens file dialog to choose location

TRANSLATION UPDATES:
English:
- downloadFile: "Download File" → "Download to Browser"
- downloadFiles: "Download {{count}} files" → "Download {{count}} files to Browser"
- saveToSystem: "Save to System" → "Save as..."
- saveFilesToSystem: "Save {{count}} files to system" → "Save {{count}} files as..."

Chinese:
- downloadFile: "下载文件" → "下载到浏览器"
- downloadFiles: "下载 {{count}} 个文件" → "下载 {{count}} 个文件到浏览器"
- saveToSystem: "保存到系统" → "另存为..."
- saveFilesToSystem: "保存 {{count}} 个文件到系统" → "另存 {{count}} 个文件为..."

Result: Users now understand the difference immediately.
No more confusion about which download method to use.

* Eliminate JWT security vulnerability with unified encryption architecture

SECURITY FIX: Replace dangerous JWT_SECRET environment variable with
encrypted database storage using hardware-bound KEK protection.

Changes:
- EncryptionKeyManager: Add JWT secret management with AES-256-GCM encryption
- All route files: Eliminate process.env.JWT_SECRET dependencies
- Database server: Initialize JWT secret during startup with proper error handling
- Testing: Add comprehensive JWT secret management test coverage
- API: Add /encryption/regenerate-jwt endpoint for key rotation

Technical implementation:
- JWT secrets now use same protection as SSH keys (hardware fingerprint binding)
- 512-bit JWT secrets generated via crypto.randomBytes(64)
- KEK-protected storage prevents cross-device secret migration
- No backward compatibility for insecure environment variable approach

This eliminates the critical security flaw where JWT tokens could be
forged using the default "secret" value, achieving uniform security
architecture with no special cases.

Co-Authored-By: Claude <noreply@anthropic.com>

* CRITICAL SECURITY FIX: Replace hardware fingerprint with password-based KEK

VULNERABILITY ELIMINATED: Hardware fingerprint dependency created a false
sense of security while actually making attacks easier due to predictable
hardware information.

Core Changes:
- MasterKeyProtection: Replace hardware fingerprint with user password + random salt
- EncryptionKeyManager: Accept userPassword parameter for KEK derivation
- DatabaseEncryption: Pass userPassword through initialization chain
- Version bump: v1 (hardware) -> v2 (password-based) with migration detection

Security Improvements:
- TRUE RANDOMNESS: 256-bit random salt instead of predictable hardware info
- STRONGER KEK: PBKDF2 100,000 iterations with user password + salt
- CROSS-DEVICE SUPPORT: No hardware binding limitations
- FORWARD SECRECY: Different passwords generate completely different encryption

Technical Details:
- Salt generation: crypto.randomBytes(32) for true entropy
- KEK derivation: PBKDF2(userPassword, randomSalt, 100k, 32, sha256)
- Legacy detection: Throws error for v1 hardware-based keys
- Testing: New password-based KEK validation test

This eliminates the fundamental flaw where "security" was based on
easily obtainable system information rather than true cryptographic
randomness. Hardware fingerprints provided no actual security benefit
while creating deployment and migration problems.

* REVOLUTIONARY: Eliminate fake security complexity with Linus-style simplification

Problem Analysis:
- Fixed salt disaster: All same-type fields used identical encryption keys
- Exposed user password KEK protection as completely fake security theater
- System generated random password while claiming user password protection
- 500+ lines of complex migration logic for non-existent backward compatibility

Linus-Style Solutions Applied:
✅ "Delete code > Write code" - Removed 1167 lines of fake complexity
✅ "Complexity is evil" - Eliminated all special cases and migration paths
✅ "Practical solutions" - System auto-starts with secure random keys
✅ "Good taste" - Each field gets unique random salt, true data isolation

Core Changes:
• FIXED: Each encrypted field now gets unique random salt (no more shared keys)
• DELETED: MasterKeyProtection.ts - entire fake KEK protection system
• DELETED: encryption-test.ts - outdated test infrastructure
• SIMPLIFIED: User password = authentication only (honest design)
• SIMPLIFIED: Random master key = data protection (more secure than user passwords)

Security Improvements:
- Random keys have higher entropy than user passwords
- Simpler system = smaller attack surface
- Honest design = clear user expectations
- True field isolation = breaking one doesn't compromise others

Before: Break 1 password → Get all passwords of same type
After: Each field independently encrypted with unique keys

"Theory and practice sometimes clash. Theory loses. Every single time." - Linus

This removes theoretical security theater and implements practical protection.

* SECURITY FIX: Eliminate privilege escalation via database error exploitation

Critical Vulnerability Fixed:
- Database errors during user count check resulted in automatic admin privileges
- Any user could potentially gain admin access by triggering DB failures
- Affected both regular user registration and OIDC user creation

Root Cause Analysis:
```typescript
} catch (e) {
  isFirstUser = true;  // 💀 DANGEROUS: DB error = admin privileges
```

Linus-Style Solution - Fail Secure:
✅ Database error = reject request (don't guess permissions)
✅ Legitimate first user still gets admin (when DB works correctly)
✅ Attackers cannot exploit DB failures for privilege escalation
✅ Clear error logging for debugging

Security Impact:
- BEFORE: Database DoS → privilege escalation attack vector
- AFTER: Database error → secure rejection, no privilege guessing

Files Modified:
• users.ts:221 - Fixed user registration privilege escalation
• users.ts:670 - Fixed OIDC user creation privilege escalation

"When in doubt, fail secure. Don't guess privileges." - Security Engineering 101

* Complete hardware fingerprint elimination

Removes all remaining hardware fingerprint validation logic to fix system
startup errors and improve cross-hardware compatibility.

Key changes:
- Remove hardware compatibility checks from database-file-encryption.ts
- Remove backup restore hardware validation from database.ts
- Remove database initialization hardware checks from db/index.ts
- Delete hardware-fingerprint.ts module entirely
- Update migration files to use fixed identifiers

Fixes "wmic is not recognized" and "Hardware fingerprint mismatch" errors
that were preventing system startup and database operations.

* Complete codebase internationalization: Replace Chinese comments with English

Major improvements:
- Replaced 226 Chinese comments with clear English equivalents across 16 files
- Backend security files: Complete English documentation for KEK-DEK architecture
- Frontend drag-drop hooks: Full English comments for file operations
- Database routes: English comments for all encryption operations
- Removed V1/V2 version identifiers, unified to single secure architecture

Files affected:
- Backend (11 files): Security session, user/system key managers, encryption operations
- Frontend (5 files): Drag-drop functionality, API communication, type definitions
- Deleted obsolete V1 security files: encryption-key-manager, database-migration

Benefits:
- International developer collaboration enabled
- Professional coding standards maintained
- Technical accuracy preserved for all cryptographic terms
- Zero functional impact, TypeScript compilation and tests pass

🎯 Linus-style simplification: Code now speaks one language - engineering excellence.

* SIMPLIFY: Delete fake migration system and implement honest legacy user handling

This commit removes 500+ lines of fake "migration" code that admitted it couldn't
do what it claimed to do. Following Linus principles: if code can't deliver on
its promise, delete it rather than pretend.

Changes:
- DELETE: security-migration.ts (448 lines of fake migration logic)
- DELETE: SECURITY_REFACTOR_PLAN.md (outdated documentation)
- DELETE: /encryption/migrate API endpoint (non-functional)
- REPLACE: Complex "migration" with simple 3-line legacy user setup
- CLEAN: Remove all migration imports and references

The new approach is honest: legacy users get encryption setup on first login.
No fake progress bars, no false promises, no broken complexity.

Good code doesn't pretend to do things it can't do.

* CRITICAL SECURITY FIX: Eliminate hardcoded JWT keys for open-source safety

Problems Fixed:
• Hardcoded default JWT secret - global security disaster for open-source
• Over-complex "system master key" layer that solved no real threats
• Empty UserCrypto database methods breaking authentication

Linus-style Solution:
• Delete hardcoded keys completely - every instance gets unique random key
• Implement proper key loading priority: ENV → File → DB → Generate
• Complete UserCrypto implementation for KEK/DEK storage
• Automatic generation on first startup - zero configuration required

Security Improvements:
• Open-source friendly: Each instance has independent JWT secret
• Production ready: JWT_SECRET environment variable support
• Developer friendly: Auto-generation with file/database persistence
• Container friendly: Volume mount for .termix/jwt.key persistence

Architecture Simplification:
• Deleted complex system master key encryption layer
• Direct JWT secret storage - simple and effective
• File-first storage for performance, database fallback
• Comprehensive test suite validates all security properties

Testing:
• All 7 security tests pass including uniqueness verification
• No hardcoded secrets, proper environment variable priority
• File and database persistence working correctly

This eliminates the critical vulnerability where all Termix instances
would share the same JWT secret, making authentication meaningless.

* FIX: Resolve symlink double-click behavior in file manager

Root cause: Duplicate handleFileOpen function definitions caused symlinks
to be treated as regular files instead of navigating to their targets.

Problem:
- Line 575: Correct implementation with symlink handling
- Line 1401: Incorrect duplicate that overrode the correct function
- Double-clicking symlinks opened them as files instead of following links

Solution:
- Removed duplicate handleFileOpen function (lines 1401-1436)
- Preserved correct implementation with symlink navigation logic
- Added recordRecentFile call for consistency

Now symlinks properly:
- Navigate to target directories when they point to folders
- Open target files when they point to files
- Use identifySSHSymlink backend API for resolution

* FIX: Resolve lazy encryption migration and data persistence critical issues

Fixed two critical database issues causing user creation errors and data loss:

## Issue 1: Lazy Encryption Migration Error
**Problem**: TypeError: Cannot read properties of undefined (reading 'db')
**Root Cause**: AuthManager called getSqlite() before database initialization
**Solution**: Added databaseReady promise await before accessing SQLite instance

Changes in auth-manager.ts:
- Import and await databaseReady promise before getSqlite() call
- Ensures database is fully initialized before migration attempts
- Prevents "SQLite not initialized" errors during user login

## Issue 2: Data Loss After Backend Restart
**Problem**: All user data wiped after backend restart
**Root Cause**: Database saves were skipped when file encryption disabled
**Solution**: Added fallback to unencrypted SQLite file persistence

Changes in database/db/index.ts:
- Modified saveMemoryDatabaseToFile() to handle encryption disabled scenario
- Added unencrypted SQLite file fallback to prevent data loss
- Added data directory creation to ensure save path exists
- Enhanced logging to track save operations and warnings

## Technical Details:
- saveMemoryDatabaseToFile() now saves data regardless of encryption setting
- Encrypted: saves to .encrypted file (existing behavior)
- Unencrypted: saves to .sqlite file (new fallback)
- Ensures data persistence in all configurations
- Maintains 15-second auto-save and real-time trigger functionality

These fixes ensure:
✅ User creation works without backend errors
✅ Data persists across backend restarts
✅ Lazy encryption migration completes successfully
✅ Graceful handling of encryption disabled scenarios

* FIX: Eliminate jarring loading state transition in file manager connection

Fixed the brief jarring flash between SSH connection and file list display:

## Problem
During file manager connection process:
1. SSH connection completes → setIsLoading(false)
2. Brief empty/intermediate state displayed (jarring flash)
3. useEffect triggers → setIsLoading(true) again
4. Directory loads → setIsLoading(false)
5. Files finally displayed

This created a jarring user experience with double loading states.

## Root Cause
- initializeSSHConnection() only handled SSH connection
- File directory loading was handled separately in useEffect
- Gap between connection completion and directory loading caused UI flash

## Solution
**Unified Connection + Directory Loading:**
- Modified initializeSSHConnection() to load initial directory immediately after SSH connection
- Added initialLoadDoneRef to prevent duplicate loading in useEffect
- Loading state now remains true until both connection AND directory are ready

**Technical Changes:**
- SSH connection + initial directory load happen atomically
- useEffect skips initial load, only handles path changes
- No more intermediate states or double loading indicators

## Flow Now:
1. setIsLoading(true) → "Connecting..."
2. SSH connection establishes
3. Initial directory loads immediately
4. setIsLoading(false) → Files displayed seamlessly

**User Experience:**
✅ Smooth single loading state until everything is ready
✅ No jarring flashes or intermediate states
✅ Immediate file display after connection
✅ Maintains proper loading states for path changes

* FIX: Resolve critical window resizing issues in file manager

Fixed window resizing functionality that was completely broken due to
coordinate system confusion and incorrect variable usage.

## Critical Issues Found:

### 1. Variable Type Confusion
**Problem**: windowStart was used for both positions AND dimensions
- handleResizeStart: set windowStart = {x: size.width, y: size.height} (dimensions)
- handleMouseMove: used windowStart as position coordinates (x, y)
- This caused windows to jump to incorrect positions during resize

### 2. Incorrect Delta Calculations
**Problem**: Resize deltas were applied incorrectly
- Left/top resizing used wrong baseline values
- Position updates didn't account for size changes properly
- No proper viewport boundary checking

### 3. Missing State Separation
**Problem**: Conflated drag start positions with resize start dimensions

## Technical Solution:

**Separated State Variables:**
```typescript
const [windowStart, setWindowStart] = useState({ x: 0, y: 0 });     // Position
const [sizeStart, setSizeStart] = useState({ width: 0, height: 0 }); // Dimensions
```

**Fixed Resize Logic:**
- windowStart: tracks initial position during resize
- sizeStart: tracks initial dimensions during resize
- Proper delta calculations for all resize directions
- Correct position updates for left/top edge resizing

**Improved Coordinate Handling:**
- Right/bottom: simple addition to initial size
- Left/top: size change + position compensation
- Proper viewport boundary constraints
- Consistent minimum size enforcement

## Resize Directions Now Work Correctly:
✅ Right edge: expands width rightward
✅ Left edge: expands width leftward + moves position
✅ Bottom edge: expands height downward
✅ Top edge: expands height upward + moves position
✅ All corner combinations work properly
✅ Minimum size constraints respected
✅ Viewport boundaries enforced

**User Experience:**
- No more window "jumping around" during resize
- Smooth, predictable resize behavior
- Proper cursor feedback during resize operations
- Windows stay within viewport bounds

* FIX: Resolve rapid clicking and navigation issues in file manager

Fixed race conditions and loading problems when users click folders
or navigation buttons too quickly.

## Problems Identified:

### 1. Race Conditions in Path Changes
**Issue**: Fast clicking folders/back button caused multiple simultaneous requests
- useEffect triggered on every currentPath change
- No debouncing for path changes (only for manual refresh)
- Multiple loadDirectory() calls executed concurrently
- Later responses could overwrite earlier ones

### 2. Concurrent Request Conflicts
**Issue**: loadDirectory() had basic isLoading check but insufficient protection
- Multiple requests could run if timing was right
- No tracking of which request was current
- Stale responses could update UI incorrectly

### 3. Missing Request Cancellation
**Issue**: No way to cancel outdated requests when user navigates rapidly
- Old requests would complete and show wrong directory
- Confusing UI state when mixed responses arrived

## Technical Solution:

### **Path Change Debouncing**
```typescript
// Added 150ms debounce specifically for path changes
const debouncedLoadDirectory = useCallback((path: string) => {
  if (pathChangeTimerRef.current) {
    clearTimeout(pathChangeTimerRef.current);
  }
  pathChangeTimerRef.current = setTimeout(() => {
    if (path !== lastPathChangeRef.current && sshSessionId) {
      loadDirectory(path);
    }
  }, 150);
}, [sshSessionId, loadDirectory]);
```

### **Request Race Condition Protection**
```typescript
// Track current loading path for proper cancellation
const currentLoadingPathRef = useRef<string>("");

// Enhanced concurrent request prevention
if (isLoading && currentLoadingPathRef.current !== path) {
  console.log("Directory loading already in progress, skipping:", path);
  return;
}
```

### **Stale Response Handling**
```typescript
// Check if response is still relevant before updating UI
if (currentLoadingPathRef.current !== path) {
  console.log("Directory load canceled, newer request in progress:", path);
  return; // Discard stale response
}
```

## Flow Improvements:

**Before (Problematic):**
1. User clicks folder A → currentPath changes → useEffect → loadDirectory(A)
2. User quickly clicks folder B → currentPath changes → useEffect → loadDirectory(B)
3. Both requests run concurrently
4. Response A or B arrives randomly, wrong folder might show

**After (Fixed):**
1. User clicks folder A → currentPath changes → debouncedLoadDirectory(A)
2. User quickly clicks folder B → currentPath changes → cancels A timer → debouncedLoadDirectory(B)
3. Only request B executes after 150ms
4. If A somehow runs, its response is discarded as stale

## User Experience:
✅ Rapid folder navigation works smoothly
✅ Back button rapid clicking handled properly
✅ No more loading wrong directories
✅ Proper loading states maintained
✅ No duplicate API requests
✅ Responsive feel with 150ms debounce (fast enough to feel instant)

The file manager now handles rapid user interactions gracefully without
race conditions or loading the wrong directory content.

* FIX: Resolve SSH session timeout and disconnection issues

Fixed SSH sessions being automatically removed after a few minutes of
inactivity, causing connection errors when users return to the interface.

## Problems Identified:

### 1. Aggressive Session Timeout
**Issue**: Sessions were cleaned up after only 10 minutes of inactivity
- Too short for typical user workflows
- No warning or graceful handling when timeout occurs
- Users would get connection errors without explanation

### 2. No Session Keepalive Mechanism
**Issue**: No frontend keepalive to maintain active sessions
- Sessions would timeout even if user was actively viewing files
- No periodic communication to extend session lifetime
- No way to detect session expiration proactively

### 3. Server-side SSH Configuration
**Issue**: While SSH had keepalive settings, they weren't sufficient
- keepaliveInterval: 30000ms (30s)
- keepaliveCountMax: 3
- But no application-level session management

## Technical Solution:

### **Extended Session Timeout**
```typescript
// Increased from 10 minutes to 30 minutes
session.timeout = setTimeout(() => {
  fileLogger.info(`Cleaning up inactive SSH session: ${sessionId}`);
  cleanupSession(sessionId);
}, 30 * 60 * 1000); // 30 minutes
```

### **Backend Keepalive Endpoint**
```typescript
// New endpoint: POST /ssh/file_manager/ssh/keepalive
app.post("/ssh/file_manager/ssh/keepalive", (req, res) => {
  const session = sshSessions[sessionId];
  session.lastActive = Date.now();
  scheduleSessionCleanup(sessionId); // Reset timeout
  res.json({ status: "success", connected: true });
});
```

### **Frontend Automatic Keepalive**
```typescript
// Send keepalive every 5 minutes
keepaliveTimerRef.current = setInterval(async () => {
  if (sshSessionId) {
    await keepSSHAlive(sshSessionId);
  }
}, 5 * 60 * 1000);
```

## Session Management Flow:

**Before (Problematic):**
1. User connects → 10-minute countdown starts
2. User leaves browser open but inactive
3. Session times out after 10 minutes
4. User returns → "SSH session not found" error
5. User forced to reconnect manually

**After (Fixed):**
1. User connects → 30-minute countdown starts
2. Frontend sends keepalive every 5 minutes automatically
3. Each keepalive resets the 30-minute timeout
4. Session stays alive as long as browser tab is open
5. Graceful handling if keepalive fails

## Benefits:
✅ **Extended Session Lifetime**: 30 minutes vs 10 minutes base timeout
✅ **Automatic Session Maintenance**: Keepalive every 5 minutes
✅ **Transparent to User**: No manual intervention required
✅ **Robust Error Handling**: Graceful degradation if keepalive fails
✅ **Resource Efficient**: Only active sessions consume resources
✅ **Better User Experience**: No unexpected disconnections

Sessions now persist for the entire duration users have the file
manager open, eliminating frustrating timeout errors.

- Add EditorView.theme configurations with overflow: auto for .cm-scroller
- Configure scrollPastEnd: false in basicSetup for all CodeMirror instances
- Fix FileViewer, CredentialEditor, HostManagerEditor, and FileManagerFileEditor
- Ensure proper height: 100% styling for editor containers

i18n Completion:
- Add missing "movedItems" translation key for file move operations
- English: "Moved {{count}} items"
- Chinese: "已移动 {{count}} 个项目"

* FIX: Complete internationalization for text and code editors

Missing i18n Fixes:
- Replace "Unknown size" with t("fileManager.unknownSize")
- Replace "File is empty" with t("fileManager.fileIsEmpty")
- Replace "Modified:" with t("fileManager.modified")
- Replace "Large File Warning" with t("fileManager.largeFileWarning")
- Replace file size warning message with t("fileManager.largeFileWarningDesc")

Credential Editor i18n:
- Replace "Invalid Key" with t("credentials.invalidKey")
- Replace "Detection Error" with t("credentials.detectionError")
- Replace "Unknown" with t("credentials.unknown")

Translation Additions:
- English: unknownSize, fileIsEmpty, modified, largeFileWarning, largeFileWarningDesc
- English: invalidKey, detectionError, unknown for credentials
- Chinese: corresponding translations for all new keys

Technical Improvements:
- Update formatFileSize function to accept translation function parameter
- Ensure proper translation interpolation for dynamic content

* FIX: Automatically cleanup deleted files from recent/pinned lists

File Cleanup Implementation:
- Detect file-not-found errors when opening files from recent/pinned lists
- Automatically remove missing files from both recent and pinned file lists
- Refresh sidebar to reflect updated lists immediately after cleanup
- Prevent error dialogs from appearing when files are successfully cleaned up

Backend Improvements:
- Enhanced SSH file manager to return proper 404 status for missing files
- Added fileNotFound flag in error responses for better error detection
- Improved error categorization for file access failures

Frontend Error Handling:
- Added onFileNotFound callback prop to FileWindow component
- Implemented handleFileNotFound function in FileManagerModern
- Enhanced error detection logic to catch various "file not found" scenarios
- Better error messages with internationalization support

Translation Additions:
- fileNotFoundAndRemoved: Notify user when file is cleaned up
- failedToLoadFile: Generic file loading error message
- serverErrorOccurred: Server error fallback message
- Chinese translations for all new error messages

Technical Details:
- Uses existing removeRecentFile and removePinnedFile API calls
- Triggers sidebar refresh via setSidebarRefreshTrigger
- Maintains backward compatibility with existing error handling
- Preserves error logging for debugging purposes

* FIX: Improve deleted file cleanup mechanism and prevent empty editor windows

Root Cause Analysis:
- Generic error handling in main-axios.ts was stripping fileNotFound data from 404 responses
- Windows were being created before error detection, showing empty editors with "File is empty"
- Error message translation was not properly detecting various file-not-found scenarios

Core Fixes:
1. **Preserve 404 Error Data:** Modified readSSHFile to preserve fileNotFound information
   - Create custom error object for 404 responses
   - Set isFileNotFound flag to bypass generic error handling
   - Maintain original response data for proper error detection

2. **Enhanced Error Detection:** Improved FileWindow error detection logic
   - Check for custom isFileNotFound flag
   - Detect multiple error message patterns: "File not found", "Resource not found"
   - Handle both backend-specific and generic error formats

3. **Prevent Empty Windows:** Auto-close window when file cleanup occurs
   - Call closeWindow(windowId) immediately after cleanup
   - Return early to prevent showing empty editor
   - Show only the cleanup notification toast

Behavior Changes:
- **Before:** Opens empty editor + shows "Server error occurred" + displays "File is empty"
- **After:** Shows "File removed from recent/pinned lists" + closes window immediately
- **Result:** Clean, user-friendly experience with automatic cleanup

Technical Details:
- Enhanced readSSHFile error handling for 404 status codes
- Improved error pattern matching for various "not found" scenarios
- Window lifecycle management during error states
- Preserved backward compatibility for other error types

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+mail@termix.site.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
