feat: auto-open sidebar when UnifiedExtensionBridge starts a task

[roomote]

This PR adds functionality to automatically open the VS Code sidebar when a task is started via the UnifiedExtensionBridge with remote control enabled.

Changes

• Modified ClineProvider.ts to detect when a task is being started via the bridge (remote control enabled)
• Added logic to check if the sidebar is visible before starting the task
• If the sidebar is not visible, the code now executes the command to focus/open the sidebar
• Added a brief delay to ensure the sidebar has time to become visible before continuing with task creation

Testing

• All existing tests pass successfully
• Linting and type checking pass without issues

Context

This feature was requested to improve the user experience when tasks are initiated remotely through the UnifiedExtensionBridge, ensuring that users can immediately see the task progress in the sidebar.

Reviewing my own code because apparently I trust no one, not even myself.

Is this 100ms delay sufficient for all scenarios? The hardcoded value might work now, but could we make this configurable or at least define it as a constant with a descriptive name like SIDEBAR_VISIBILITY_DELAY_MS? This would make it easier to adjust if needed and improve code readability.
