refactor: Enhance Cursor app modification with improved file handling and signing

- Replaced `cp` with `rsync` for more robust file copying
- Added detailed logging for file modification steps
- Improved file permission management during modification
- Enhanced codesign process with better metadata preservation
- Added LaunchServices database rebuild after modification
- Improved error handling and user guidance for signing issues
- Temporarily disabled restore feature for future refinement
