refactor(navigator): migrate all 13 consumers off useNavigator god-hook

Mechanical swap to the new filter hooks landed in the previous commits:
- NavigatorDoorStateView -> useDoorState (snapshot/setSnapshot/reset)
- NavigatorView -> useNavigatorData + useNavigatorUiState +
  useNavigatorActions + direct useNavigatorUiStore.getState() in handlers
  (linkTracker collapsed to a dispatch table; 9 useState gone)
- NavigatorSearchView -> useNavigatorData + useNavigatorActions
  (sendSearch prop drilling removed)
- NavigatorSearchResultItemView -> useDoorState (setSnapshot aliased as
  setDoorData; call sites unchanged - DoorStateSnapshot is compatible)
- 9 bulk consumers (one-line import swap) -> useNavigatorData

Zero behavioural change intended. yarn typecheck + yarn test --run +
yarn lint:hooks all clean on this commit.
