publish_prepare
Prepare a publish package
Create reviewable publish packages for an episode or clip. This never publishes externally; a fresh server-bound final confirmation is required before any send and is ordinarily surfaced in the first-party workspace. App-only descriptor visibility does not itself restrict authenticated MCP transport or prove human review. Put improved YouTube/LinkedIn/X titles, descriptions, and copy here (or in publish_update) rather than mutating the saved episode with episode_update.
