Instead of chmod on every app start, catch EACCES (error 13) when
spawning sidecar or ffmpeg, fix permissions, then retry once:
- sidecar spawn: catches permission denied, runs set_executable_permissions
on the sidecar dir, retries spawn
- ffmpeg: catches permission denied, chmod +x ffmpeg and ffprobe, retries
Zero overhead on normal launches. Only fixes permissions when actually needed.

Previously only the main sidecar binary got chmod 755. Now all files
in the extraction directory get execute permissions — covers ffmpeg,
ffprobe, and any other bundled binaries. Applied in three places:
- sidecar/mod.rs: after local extraction
- commands/sidecar.rs: after download extraction
- commands/media.rs: removed single-file fix (now handled globally)

The bundled ffmpeg in the sidecar extract dir lacked execute permissions.
Now sets chmod 755 on Unix when find_ffmpeg locates the bundled binary.

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

AI provider:
- Extract configureAIProvider() from saveSettings for reuse
- Call it on app startup after sidecar is ready (was only called on Save)
- Call it after first-time sidecar download completes
- Sidecar now receives correct Ollama URL/model immediately
Video extraction:
- Hide ffmpeg console window on Windows (CREATE_NO_WINDOW flag)
- Show "Extracting audio from video..." overlay with spinner during extraction
- UI stays responsive while ffmpeg runs

Video files (MP4, MKV, etc.) are now processed with ffmpeg to extract
audio to a temp WAV file before loading into wavesurfer. This prevents
the WebView crash caused by trying to fetch multi-GB files into memory.
- New extract_audio Tauri command uses ffmpeg (sidecar-bundled or system)
- Frontend detects video extensions and extracts audio automatically
- User-friendly error if ffmpeg is not installed with install instructions
- Reverted wavesurfer MediaElement approach in favor of clean extraction
- Added FFmpeg install guide to USER_GUIDE.md
