Enhance file monitoring for LoRA files

- Added a method to map symbolic links back to actual paths in the Config class.
- Improved file creation handling in LoraFileHandler to check for file size and existence before processing.
- Introduced handling for file modification events to update the ignore list and schedule updates.
- Increased debounce delay in _process_changes to allow for file downloads to complete.
- Enhanced action processing to prioritize 'add' actions and verify file existence before adding to cache.
