Last task of Phase 5. The app now has the full bottom-bar shell with
NavHost wiring.
- nav/Routes.kt — @Serializable destinations: top-level tabs
(Home/Library/Search/Settings), detail screens with id args
(AlbumDetail, ArtistDetail, PlaylistDetail), overlays
(NowPlaying, Queue, Login).
- nav/MinstrelNavGraph.kt — NavHost with composable<RouteType>()
destinations. Library wires to the real LibraryScreen; everything
else uses the shared EmptyState as a "Coming soon" placeholder.
- MainActivity — Scaffold with NavigationBar bottom bar.
Selected-tab tracking via currentBackStackEntryAsState +
NavDestination.hasRoute(KClass) (type-safe routes API in
nav-compose 2.8+).
- Library cards' onArtistClick / onAlbumClick now navigate to
ArtistDetail(id) / AlbumDetail(id) — stubs for now, lit up when
those detail screens land.
Bottom-bar icons (Lucide CMP):
- House, LibraryBig, Search, Settings
startDestination = Library so the new UI is the cold-start landing
spot until the Home screen lands in Phase 6.
