Subject: [PATCH] refactor: Enhance Cursor app modification script with robust
 backup and replacement mechanism

- Improved application replacement process with sudo-based file operations
- Added comprehensive backup creation before app modification
- Enhanced error handling during app replacement and restoration
- Simplified temporary file cleanup and permission management
- Removed code signing verification step
- Streamlined sudo usage for critical file operations
