Streaming matching: add artist gate rejecting candidates with artist
similarity below 0.4, raise threshold to 0.60, block fallback to
Soulseek filename matcher for Tidal/Qobuz/HiFi/Deezer. Fix single-
char artist containment bug where normalize_string strips non-ASCII
(e.g. "B小町" → "b") causing "b" to match any artist containing
that letter. Fixed in both score_track_match and the Soulseek scorer.
YouTube and Soulseek matching behavior unchanged.
Global search: add registerSearchDownload() calls to _gsClickAlbum
and _gsClickTrack so downloads create bubble snapshots on dashboard
and search page, matching the enhanced search standard.
Global search escaping: add _escAttr() helper to handle newlines in
album/artist names that broke inline onclick string literals.
