Meeting citations, down to the exact quote

TL;DR: Add meeting transcripts to a chat and follow citations back to the exact moments in your recordings. Hover over a timestamp to read the quoted passage, listen to it, or open the transcript at that moment.

New Features & Enhancements

• Meeting citations: Meeting reports and chats with attached transcripts can now include timestamp citations. Hover over a citation to see the quoted passage and speaker, play the excerpt, or jump to that moment in the transcript.

Bug Fixes & Stability

• Speaker identification: Review conflicting speaker matches and reduce incorrect automatic speaker names.
• Transcription: Regenerating a transcript waits for the speech model to be ready, preserves progress and sidebar selection, and reports failures more reliably.
