Optimize syncback process and enhance patch selection logic

- Improved the syncback functionality by detecting unchanged output file hashes to avoid unnecessary writes, optimizing performance for larger projects.
- Updated the patch selection logic to ensure that auto-selection only occurs when the current selection matches the default, enhancing user experience during patch reviews.

These changes aim to streamline file synchronization and improve the clarity of patch management in the application.
