Added
- Audio File Support: Added full support for importing and converting standalone audio files (MP3, WAV, FLAC, M4A, AAC).
- Smart UI Adaptation: The interface now automatically adapts when an audio file is selected:
- Tab Management: The "Video" tab is automatically disabled.
- Container Filtering: Video containers (MP4, MKV, etc.) are disabled in the output settings to prevent invalid configurations.
- Preset Filtering: Incompatible video presets are visually disabled in the presets library.
- Auto-Format Switching: Importing an audio-only file automatically switches the output configuration to a compatible audio format (e.g., MP3) if a video container was previously selected.
