- Swap Task 5/6 order so get_all_export_paths exists before UI uses it
- Remove cosine similarity clamping to preserve anti-correlation signal
- Use os.path.exists instead of os.path.isfile (handles image sequences)
- Add worker cleanup to disconnect stale signals before new scan
- Remove lock from get_all_export_paths (matches read-only convention)
- Always use get_all_export_paths for Current Profile (not current-file-first)
- Filter export paths with os.path.exists for deleted files
- Use abs() for float comparison in tests instead of ==
- Add cancel_flag to ScanWorker and scan_video for interruptible scans
