fix(macos): hide overlay when mpv loses foreground and open stats inacti

- Add "active" Swift helper output when mpv is frontmost but geometry is temporarily unavailable, preserving overlay through transient tracker misses
- Use showInactive for overlay and stats window on macOS to avoid switching Spaces over fullscreen mpv
- Disable autoInstallOnAppQuit to prevent premature Squirrel install before user confirms restart
