v3.0.1 — Meeting Mode improvements

Meeting Mode

• Mic auto-start — microphone enables automatically when meeting starts
• Mic button states — green 🎤 active, red strikethrough inactive
• Token rotation — tab + mic Deepgram WS rotated every 70s (prevents 90s TTL death)
• KeepAlive — Deepgram keepalive every 8s prevents NET-0001 timeout during silence
• Sequential translation queues — per-channel queue (depth 5) prevents out-of-order subtitles
• Chat-style overlay — mic/You on right (green), Speaker on left
• Restricted URL guard — meeting mode blocked on chrome:// / about: pages
• Fix — speechLanguage=auto no longer skips mic translation
• Fix — mic button disabled during async toggle (no double-click race)
• Fix — mic state resets correctly on ENDED and Resume
