feat(navigator): drive search via TanStack Query + setTab/setFilter UI store

NavigatorView reads searchResult/isFetching from useNavigatorSearch
instead of useNavigatorData/useNavigatorUiState. Tab clicks call
setTab(code) on the UI store, which atomically updates the query key
and triggers refetch. The 4 lifecycle useEffect blocks driving the
old imperative flow (needsSearch / reloadCurrentSearch / markReady)
are removed — the query handles all of it now.

NavigatorSearchView has a debounced (300ms) onChange -> setFilter
that drives the same query refetch. Explicit submit (Enter / button)
skips the debounce and calls setFilter immediately.

linkTracker case 'search' now setTab + setFilter + show — no more
pendingSearch ref.

useNavigatorSearch.test.tsx: cast constructors as any to satisfy tsgo
against real renderer types while keeping runtime stubs no-arg-safe.

yarn typecheck / test / lint:hooks all clean (only pre-existing
floorplan environmental failures).
