Default !similar now discovers similar artists/tracks, resolves each
against YouTube in parallel via ThreadPoolExecutor, fades out current
playback, and starts the new playlist. Old display behavior moves to
!similar list subcommand.
New helpers: _search_queries() normalizes Last.fm/MB results into search
strings, _resolve_playlist() resolves queries to _Track objects in
parallel. Falls back to display mode when music plugin not loaded.

_current_meta now checks registry._bots for peer bot music state
when the current bot has nothing playing. Fixes merlin reporting
"Nothing playing" while derp is actively streaming.

Remove early return on missing Last.fm API key. Both commands now
fall back to MusicBrainz (mb_search_artist -> mb_artist_tags ->
mb_find_similar_recordings) when no API key is configured or when
Last.fm returns empty results. Same pattern used by discover_similar.

Every Nth autoplay pick (configurable via discover_ratio), query Last.fm
for similar tracks. When Last.fm has no key or returns nothing, fall back
to MusicBrainz tag-based recording search (no API key needed). Discovered
tracks are resolved via yt-dlp and deduplicated within the session. If
discovery fails, the kept-deck shuffle continues as before.

Music:
- #random URL fragment shuffles playlist tracks before enqueuing
- Lazy playlist resolution: first 10 tracks resolve immediately,
remaining are fetched in a background task
- !kept repair re-downloads kept tracks with missing local files
- !kept shows [MISSING] marker for tracks without local files
- TTS ducking: music ducks when merlin speaks via voice peer,
smooth restore after TTS finishes
Performance (from profiling):
- Connection pool: preload_content=True for SOCKS connection reuse
- Pool tuning: 30 pools / 8 connections (up from 20/4)
- _PooledResponse wrapper for stdlib-compatible read interface
- Iterative _extract_videos (replace 51K-deep recursion with stack)
- proxy=False for local SearXNG
Voice + multi-bot:
- Per-bot voice config lookup ([<username>.voice] in TOML)
- Mute detection: skip duck silence when all users muted
- Autoplay shuffle deck (no repeats until full cycle)
- Seek clamp to track duration (prevent seek-past-end stall)
