fix(mac): restore right-click status-item menu on macOS 27 (#472)

Present the right-click menu from a global right-mouse-down monitor (hit-tested against the status-item window) via NSMenu.popUp, since macOS 27 no longer routes right-mouse events to the status-item action. Legacy action path retained for macOS <= 26, guarded by a debounce. Remove the global monitor on terminate.
