+/// <summary>
+/// TASK 20 integration: global hotkeys reach their commands. A real MainWindow
+/// attaches the GlobalHotkeyManager (fake registrar — no OS-wide registration in
+/// tests); posting a genuine WM_HOTKEY through the window's own HwndSource hook
+/// must stage the mapped scene and flip the mic mute. Closing must revoke every
+/// registration made.
