- Choose Windows vs WSL execution based on where the video file lives
- Windows-host videos (/mnt/c, /mnt/d, C:, D:) should use PowerShell and Windows-local transcription project
- WSL/Linux videos (/home, /var, Linux mounts) should use Linux/WSL commands
- Keep Windows uv UNC-path warning, but only when Windows execution is chosen
- Add reference doc with Windows and WSL command templates
