Visual polish, first wave:
- NavigatorEmptyStateView: replaces the bare "No rooms found" text with a
centered icon + message + a Create-room CTA. Reuses existing i18n keys
(navigator.search.returned.no.results / .roomsettings.moderation.none /
.createroom.create) so no new localization entries are needed.
- NavigatorSearchSkeletonView: animate-pulse placeholder rows shown while a
search is in flight and no result is cached yet (matches the HK dashboard
skeleton pattern). Replaces the NitroCard.Content spinner overlay for the
result list.
Bug fix bundled in: NavigatorSearchView called useNavigatorSearch() a second
time purely to read searchResult for its input-sync effect. Since the hook is
not a useBetween singleton, that registered a duplicate NavigatorSearchEvent
listener AND fired a duplicate NavigatorSearchComposer on every search.
NavigatorView now owns the single useNavigatorSearch() call and passes
searchResult to NavigatorSearchView via prop.
Test maintenance: useNavigatorSearch.test.tsx was written for the original
useNitroQuery implementation, which upstream reverted (05d71dd1) to
useMessageEvent + useState. Removed the dead QueryClient scaffolding, fixed
case 1 (assert no fetch starts with empty tab), dropped case 7 (the query
invalidator no longer exists). 6 cases, all green.
Full suite 471/471. Typecheck: only the environmental renderer-mismatch
errors (soundboard / rare-values / floorplan APIs absent from the linked
renderer), none in navigator files.
