episode_update

Update episode metadata

Updates the saved episode's own title, description, Episode-time chapters, and/or Episode date. Requires the Episode's draft_revision from episode_read; a stale token fails without overwriting newer human copy. Episode date is the durable project chronology field; date-only input is interpreted as 12:00 UTC and sets the basis to manual. This is metadata-only; structural timeline edits use the separate episode_edit patch primitive. It changes the episode itself; YouTube/LinkedIn/X package copy belongs to publish_prepare and publish_update.
