Adds the Discover surface — Lidarr search bar over an out-of-library
artist suggestion feed, with offline-first request-creation through
the MutationQueue. Mirrors `flutter_client/lib/discover/discover_screen.dart`.
New:
- models/wire/DiscoverWire.kt — LidarrSearchResultWire,
ArtistSuggestionWire (with SeedContribution children), and the
CreateRequestBody POST shape.
- models/Discover.kt — domain refs + LidarrRequestKind enum.
ArtistSuggestionRef.attributionText preserves the Oxford-comma,
"Because you liked X / played Y" phrasing from Flutter.
- api/endpoints/DiscoverApi.kt — Retrofit: GET /api/discover/suggestions,
GET /api/lidarr/search (q + kind), POST /api/requests.
- discover/data/DiscoverRepository.kt — read-through search +
suggestion + offline-first createRequest. Returns
RequestOutcome.ACCEPTED on 2xx, RequestOutcome.QUEUED when the
call got buffered into the MutationQueue. Same swallowed-exception
rationale as LikesRepository.toggleLike.
- discover/ui/DiscoverScreen.kt — VM + state + composable. Filter
chips for Artists / Albums kind, search field with ImeAction.Search
submit, results list vs. suggestion feed swap based on whether
the query box is empty. Snackbar wording switches between
"Requested: X" and "Request queued: X" based on outcome.
Locally-just-requested MBIDs are tracked so the "Request" affordance
swaps to a "Requested" pill instantly without waiting for a server
refetch.
Modified:
- cache/mutations/MutationQueue.kt — adds MutationKind.REQUEST_CREATE
+ RequestCreatePayload + enqueueRequestCreate helper.
- nav/MinstrelNavGraph.kt — Discover route swaps from ComingSoon to
`DiscoverScreen(navController = navController)`.
Requests screen (your-own requests list with status/cancel) and the
admin/quarantine slices land in follow-up commits within this phase.
