    Script: uninstall_vaila_win.ps1
    Description: Uninstalls the vaila - Multimodal Toolbox from Windows. Removes the
                 uv virtual environment (.venv), program files, FFmpeg if installed,
                 Windows Terminal 'vaila' profile, and Start Menu / Desktop shortcuts.
                 Legacy Conda environments (if any) are detected and removed best-effort,
                 but conda is no longer the supported install path.
