Add video support and improve mpv process management

- Enable video playback by removing --no-video flag
- Add --profile=fast for better performance
- Add --audio-display=no to prevent cover art windows
- Implement mpv process respawn when closed
- Add process death detection and cleanup
- Show refresh status immediately in title bar
- Fix playlist playback after clearing
