TrackState.searchArtists/searchAlbums/searchPlaylists were only ever written
empty (the metadata-search parse loops iterated const [] lists and customSearch
set []), so the home feed's separate artist/album/playlist result sections
never rendered. Drop the fields, the dead parse loops and _parseSearch* helpers,
the SearchArtist/Album/Playlist models, the sort caches/methods, and the
_Search* result widgets. The live tracks->buckets sections (_CollectionItemWidget
via artistItems/albumItems/playlistItems) and the search filter tabs are kept.
