Projects now save as folders containing .vtn + audio.wav:

My Transcript.vtn
audio.wav
Audio handling:
- Always extract to 22kHz mono WAV on import (all formats, not just video)
- Prevents WebAudio crash from decoding large MP3/FLAC/OGG to PCM in memory
- WAV saved alongside .vtn on project save (moved from temp)
- Sidecar still uses original file (does its own conversion)
Project format v2:
- source_file: original import path (for re-extraction)
- audio_wav: relative path to extracted WAV (portable)
Re-link on open:
- If audio.wav exists → load directly
- If missing but source exists → re-extract automatically
- If both missing → dialog to locate file via file picker
- V1 project migration: extracts WAV on first open
New Rust commands: check_file_exists, copy_file, create_dir
extract_audio: now accepts optional output_path, uses 22kHz sample rate
