- Implemented RenameService for handling file renaming with features like name validation, proposed name generation, conflict detection, and atomic rename operations.
- Created utility modules for language code extraction, regex pattern matching, and frame class matching to centralize common functionalities.
- Added comprehensive logging for error handling and debugging across all new modules.
