The Flutter Discover screen was Lidarr-search-only; its empty state
showed a "Type to search" placeholder while web's /discover renders
the LB-derived out-of-library artist SuggestionFeed as its default
surface. Parity gap that slipped #356.
- ArtistSuggestion/SeedContribution model mirroring web types, with
attributionText() matching web's "Because you liked/played X[, Y, and
Z]." (Oxford comma, max 3).
- DiscoverApi.listSuggestions() → GET /api/discover/suggestions
(image_url already resolved server-side from Lidarr, a7bea43).
- discover_screen: empty search box → suggestions feed (artist art +
name + attribution + Request, reusing the existing createRequest +
mutation-queue-replay flow with optimistic hide); typing → Lidarr
search replaces; clearing → suggestions return. Mirrors web exactly.
Flutter-only; server endpoint unchanged.
