Nobody should publish a stable release from the GitHub UI, and once
immutable releases land that mistake is permanent: the release stays on
the attempt ref with no receipt tag, no feed move, and no alias move.
The draft now carries a fenced caution above and below the generated
notes, and publish strips both fences before the release goes public,
refusing an unbalanced fence. The notes are fetched from the API and
written to a file because --generate-notes cannot place text below the
notes.
