Native application menu: standard App / Edit / View / Window / Help structure, no browser verbs (no Reload, no zoom, no Back), plus app-defined groups.
Donors: ViewRight’s macOS menu (Hide, Hide Others, Quit, Edit, Window), CodeRight’s
build_application_menu (typed ids forwarded to the renderer exactly once) and HeardRight’s
menu/tray gating. Custom items carry stable string ids; a click is delivered as the
rightkit-shell://menu event and to an optional Rust callback.
