fix(cliproxy): improve sync robustness and consistency

- Add timeout warning in restartAutoSyncWatcher when sync exceeds 10s
- Improve YAML key detection with regex pattern for safer parsing
- Replace --force help with --verbose (no confirmation prompt exists)
- Add force flag parsing for future use
