feat(code-actions): add "Fix Code in Current Task" action

Adds ability to fix code within the context of an active task instead of starting a new one. This allows for more efficient workflow when already working with Roo.

Add new FIX_IN_CURRENT_TASK code action and command
Enhance ClineProvider to support context-aware code fixing
Update tests to verify new action functionality
