fix: improve file existence checks and error handling (#696)

- Add file existence validation for open tabs and file listings to filter out deleted files
- Wrap ignore file watcher creation in try-catch to handle missing files gracefully
- Update chat UI to hide rate limit retries and empty messages for cleaner UX
- Enhance error logging throughout the application for better debugging
