- File metadata display (duration, size, format)
- Editable meeting titles
- Progress tracking with visual indicators
- Smart template selection
- Auto-navigation to Transcription view
- Updated README with BlackHole requirement and Teams config
- Added get_audio_metadata Rust command
- Version bump to 1.1.0
