Summary of Changes

Hello @LukeGus, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This PR introduces a comprehensive 'terminal snippets' feature, enabling users to manage and execute saved commands via a new sidebar UI. It includes full-stack implementation, from database schema and API endpoints to frontend components and internationalization.

Highlights

Intent: This pull request introduces a new 'terminal snippets' feature, allowing users to save, manage, and quickly execute common commands directly within the terminal interface. It includes both backend API support and a frontend sidebar UI for interaction.
Key Changes: The changes span across backend, frontend, and internationalization files:

Backend API & Database:
- A new snippets table is added to the database schema (src/backend/database/db/index.ts, src/backend/database/db/schema.ts) to store user-specific command snippets (name, content, description, timestamps).
- New RESTful API endpoints (/snippets) are implemented in src/backend/database/routes/snippets.ts for CRUD operations (create, read, update, delete) on snippets, including authentication and data access control.
- The main backend application (src/backend/database/database.ts) is updated to import and use these new snippet routes.
Frontend UI & Logic:
- New TypeScript interfaces (Snippet, SnippetData) are defined in src/types/index.ts for type safety.
- A new React component, SnippetsSidebar.tsx, is added (src/ui/Desktop/Apps/Terminal/SnippetsSidebar.tsx). This component provides the user interface for viewing, creating, editing, deleting, executing, and copying snippets.
- The TopNavbar.tsx component (src/ui/Desktop/Navigation/TopNavbar.tsx) is updated to include a new button to toggle the SnippetsSidebar. This button is enabled only when a terminal tab is active, and it integrates the functionality to send snippet content to the active terminal.
- New API client functions (getSnippets, createSnippet, updateSnippet, deleteSnippet) are added to src/ui/main-axios.ts to interact with the backend snippet endpoints.
Internationalization:
- New translation keys for the 'snippets' feature, including UI labels, placeholders, validation messages, and success/error messages, are added to src/locales/en/translation.json and src/locales/zh/translation.json.

The route parameter id is used with parseInt without validation. If id is not a string that can be parsed into a number (e.g., an empty string or non-numeric characters), parseInt will return NaN. This could lead to unexpected behavior or errors in the database query. You should validate that id is a valid number before using it.

This same validation should be applied to the PUT /:id and DELETE /:id routes as well.

    const { id } = req.params;
    const snippetId = parseInt(id, 10);

    if (!isNonEmptyString(userId) || isNaN(snippetId)) {
      authLogger.warn("Invalid request for snippet fetch: invalid ID", { userId, id });
      return res.status(400).json({ error: "Invalid request parameters" });
    }

The update endpoint allows setting name and content to empty strings, which is inconsistent with the creation endpoint that requires non-empty strings via isNonEmptyString. You should add validation to ensure name and content are not empty if they are being updated.

Additionally, you can avoid using any for updateFields by using a more specific type like Partial<typeof snippets.$inferInsert> for better type safety.

      const updateFields: Partial<typeof snippets.$inferInsert> = {
        updatedAt: sql`CURRENT_TIMESTAMP`,
      };

      if (updateData.name !== undefined) {
        if (!isNonEmptyString(updateData.name)) {
          return res.status(400).json({ error: "Name cannot be empty" });

To improve efficiency, you can use Drizzle's .returning() method on the update query. This will return the updated record in a single database call, avoiding the need for a separate select query.

      const updated = await db
        .update(snippets)
        .set(updateFields)
        .where(and(eq(snippets.id, parseInt(id)), eq(snippets.userId, userId)))
        .returning();

To improve type safety and maintainability, you should use the specific Snippet and SnippetData types for the parameters and return values of these API functions instead of any. You'll need to add Snippet and SnippetData to your imports from ../types/index.js.

export async function getSnippets(): Promise<Snippet[]> {
  try {
    const response = await authApi.get<Snippet[]>("/snippets");
    return response.data;
  } catch (error) {
    throw handleApiError(error, "fetch snippets");
  }
}

export async function createSnippet(snippetData: SnippetData): Promise<Snippet> {
  try {
    const response = await authApi.post<Snippet>("/snippets", snippetData);
    return response.data;
  } catch (error) {
    throw handleApiError(error, "create snippet");
  }
}

export async function updateSnippet(
  snippetId: number,
  snippetData: Partial<SnippetData>,
): Promise<Snippet> {
  try {
    const response = await authApi.put<Snippet>(
      `/snippets/${snippetId}`,
      snippetData,
    );
    return response.data;
  } catch (error) {
    throw handleApiError(error, "update snippet");
  }
}

export async function deleteSnippet(snippetId: number): Promise<{ success: boolean }> {
  try {
    const response = await authApi.delete<{ success: boolean }>(
      `/snippets/${snippetId}`,
    );
    return response.data;
  } catch (error) {
    throw handleApiError(error, "delete snippet");
