Replaces the Search-route ComingSoon stub with the real
three-facet search. Mirrors `flutter_client/lib/search/search_screen.dart`.
New:
- models/wire/SearchWire.kt — three concrete PagedXxxWire types
(Artists / Albums / Tracks) wrapping the server's Page[T] envelope,
plus SearchResponseWire. Going non-generic on the paged wrapper is
fine — three call sites and the explicit types read clearer than
a generic with manual type-arg gymnastics at decode time.
- models/SearchResponseRef.kt — domain envelope with `isEmpty` for
the screen's "no matches" branch.
- api/endpoints/SearchApi.kt — Retrofit GET /api/search with q +
limit + offset.
- search/data/SearchRepository.kt — trivial wire→domain mapper;
debouncing intentionally lives in the VM.
- search/ui/SearchViewModel.kt — 250ms debounce on the query Flow
via debounce() + distinctUntilChanged(). Empty query collapses
to Idle without firing a request. `playTrack(track)` queues a
single track via PlayerController for the same single-row-play
pattern as HistoryTab.
- search/ui/SearchScreen.kt — auto-focus the field on entry (the
user typed Search to start typing), inline X button to clear.
Results render as three sections (Artists / Albums / Tracks),
each section omitted when its list is empty. Artist taps →
ArtistDetail, album taps → AlbumDetail, track taps → play.
Modified:
- nav/MinstrelNavGraph.kt — Search route renders the real screen.
