- Add `src/hooks/rooms/widgets/useDoorState.ts`: useBetween-based
singleton wrapping DoorbellMessageEvent / RoomDoorbellAcceptedEvent /
FlatAccessDeniedMessageEvent / GenericErrorEvent /
GetGuestRoomResultEvent; all 5 handlers wrapped in useCallback([])
so their references are stable across useBetween tick() calls and
the effect dep-array never triggers re-registration.
- Add `src/hooks/rooms/widgets/useDoorState.test.tsx`: 11-case Vitest
suite (initial state, 5 event transitions, 2 no-op guards,
GetGuestRoomResultEvent doorbell/password paths, reset()).
- Extend `src/nitro-renderer.mock.ts`: new MessageEvent base class with
callBack/type/getParser; DoorbellMessageEvent / RoomDoorbellAcceptedEvent /
FlatAccessDeniedMessageEvent / GenericErrorEvent / GetGuestRoomResultEvent
concrete stubs; RoomDataParser.DOORBELL_STATE + PASSWORD_STATE; separate
msgListeners map (cleared independently of NitroEvent listeners so
useBetween subscriptions survive between test cases); WeakMap wrapper
for correct removeMessageEvent; GetCommunication routes to msgListeners.
All 11 useDoorState tests pass; full suite 453/456 (3 pre-existing
FloorplanCanvasSVG jsdom/SVG-CTM failures unrelated to this task).
