Release v2.11.8

• Retry stalled initial voice handshakes within a bounded wait, share concurrent joins, and report the failed network phase without exposing voice credentials.
• Connect before queueing new requests so failed voice joins do not leave unexpected tracks behind.
• Handle Discord audio resource errors without crashing Muse and continue normal queue advancement.
• Keep chapter and SponsorBlock cache boundaries separate so short cached excerpts cannot truncate full tracks. Existing audio caches refill as needed.
• Apply SponsorBlock trimming within each chapter's original timestamps so split tracks play the correct audio.
• Ignore stale listener-departure events after the voice connection or channel changes.
• Prevent early YouTube playlist metadata failures from becoming unhandled rejections while later pages load.
• Refresh expired metadata without racing concurrent requests to delete the same cache row.
• Validate PR snapshot provenance before granting publishing access and restrict snapshot tags to the corresponding PR preview.
• Resolve SoundCloud tracks, share links, and bounded playlists with yt-dlp instead of probing HTML pages as audio streams, and refresh media URLs when playback begins.
