/**
 * desktop/src/menu.ts — the native application menu.
 *
 * Built entirely from Electron's built-in roles (copy/paste/reload/zoom/…) so it
 * needs no cooperation from the (unchanged) frontend. There are deliberately no
 * page-driving custom actions here — the desktop shell adds native chrome, not
 * new terminal behaviour. The caller passes the result to Menu.setApplicationMenu.
