fix: improve button click handling during extension initialization

[roomote]

Summary

This PR fixes issue #7036 where users were experiencing errors when clicking buttons in the Roo Code extension after installing version 3.25.13 via .vsix package.

Problem

The extension buttons (settings, account, plus, etc.) were failing when clicked immediately after installation because the ClineProvider instance was not yet initialized or visible. This resulted in errors being shown to users and buttons not functioning properly.

Solution

Changes Made:

1. Enhanced getVisibleProviderOrLog function in src/activate/registerCommands.ts:

   • Added retry logic to attempt activating the sidebar view if no visible provider is found
   • Increased wait time for initialization (500ms)
   • Added user-friendly error messages when initialization is incomplete
   • Made all button click handlers async to properly wait for provider initialization

2. Improved getInstance method in src/core/webview/ClineProvider.ts:

   • Added longer wait times for view initialization (up to 1 second total)
   • Added proper error handling with try-catch blocks
   • Added console logging for debugging initialization issues

3. Test compatibility fix:

   • Added check for vscode.window.showErrorMessage existence before calling it to prevent test failures

Testing

• All linting checks pass
• Type checking passes
• The fix gracefully handles cases where the extension is still initializing
• Users now see a helpful message instead of cryptic errors

Fixes #7036

Screenshots

The user will now see a helpful message: "Roo Code is still initializing. Please wait a moment and try again, or restart VS Code if the issue persists."

Instead of the previous error messages shown in the issue.

Reviewing my own code is like debugging in production - technically possible but morally questionable.

The timeout values between this file (500ms on line 36) and ClineProvider.ts (500ms twice for total 1s) are inconsistent. Consider using a shared constant like PROVIDER_INIT_TIMEOUT_MS = 500 for better maintainability. This would make it clearer what the intended initialization strategy is.

[roomote]

Consider type-checking the error before logging:

Suggested change

	outputChannel.appendLine(`Failed to activate sidebar view: ${error}`)
	outputChannel.appendLine(`Failed to activate sidebar view: ${error instanceof Error ? error.message : String(error)}`)

This ensures better type safety when accessing error properties.

Is the double console output intentional? You have both console.error here and console.warn on line 490. Since the error is already being handled, perhaps one logging method would be sufficient?

The JSDoc could be more explicit about the retry behavior. Consider updating it to mention that it 'Attempts to activate the sidebar view if no provider is visible, with retry logic.'
