Backend: - Migration 17: similar_artist_map table stores per-artist similar artist relationships (source_mbid → similar_mbid + name + score) - Tier 4 index build now persists similar artists to this table - GetLibrarySimilarArtists(mbid) queries similar artists filtered by JOIN with the artists table (library-only, no API calls) - Added db field to explore.Service for direct queries Frontend: - ExploreSettingsStore with libraryOnly toggle, persisted to localStorage - Top bar toggle button with active/inactive styling - Explore search: skips full MB/LB pipeline when library-only, uses only searchLibraryCache (pure JS, instant) - Artist detail page: in library-only mode, skips all API calls (no top tracks, no top releases, no LB play count, no MB artist lookup). Uses library store for discography, calls GetLibrarySimilarArtists for similar artists. - Similar artists section: changed from horizontal scroll to wrapping flex layout with collapsible toggle (Show all N) - Removed debug artist ranking log
