feat(git): expand core git repository management features

This update significantly expands the available Git functionality by adding robust support for initializing repositories, managing remotes, and improving complex workflow operations like merging and reverting commits. New API endpoints are exposed across the backend and frontend to handle remote setup, branch tracking, and conflict resolution workflows.

- Added full remote management capabilities (add, update, remove).
- Implemented advanced merge strategies and commit reversion logic.
- Introduced a dedicated UI component for synchronization settings.
