feat: data lifecycle rewrite, download clients, wanted list, and central catalog index
Ships the fresh-start schema cleanup: rebuilt explore catalog index
pipeline (dump import, artifact fetch/build, incremental listen-count
refresh), a new download subsystem (Lidarr/Prowlarr/qBittorrent/SABnzbd/
slskd/yt-dlp providers, staging, reconciliation, wanted list), and the
supporting schema/query/store changes across backend and frontend.

Also includes two smaller follow-ups: bump the central index's
rebuild-after cadence from 90 to 180 days, and remove the Explore
"library only" online/offline toggle entirely (frontend-only, no
backend counterpart) rather than carry unused UI/state.

-- Contentless FTS5 index over recording lyrics, enabling
-- "search by a lyric fragment → find the song". The rowid is
-- recordings.id. Only recordings with non-empty lyrics are indexed.
--
-- content='' means the lyric text itself is NOT stored a second time
-- (it already lives in recordings.lyrics); the index keeps only the
-- tokenised inverted index, so it stays compact even for large
-- libraries. contentless_delete=1 lets us delete/reinsert a single
-- row when a track's lyrics change (scan update or LRCLIB backfill).
CREATE VIRTUAL TABLE IF NOT EXISTS lyrics_index USING fts5(
lyrics,
content='',
contentless_delete=1,
tokenize='unicode61 remove_diacritics 2'
);
