Fixes#289
- transcripts list: drop removed TranscriptsQueryScope type (scope is a
String in the live schema), require [String!] for organizers and
participants, add title/organizer-email/participant-email filters
- bites create: use the live transcript_Id argument name and the
BitePrivacy enum (public, team, participants)
- add ergonomic commands for documented gaps found in the audit:
askfred get, meetings update-channel, meetings share --expiry-days,
live add-to (addToLiveMeeting), live soundbite (createLiveSoundbite),
audio create-upload/confirm-upload (two-phase upload), users set-role
- add eval manifest (5 cases) to satisfy the modified-skill eval ratchet
- update SKILL.md, cli-reference, api-reference, source-index, workflows
to match the audited surface and record the 2026-08-05 schema audit
