revert(digest): keep the agents digest at main's bytes; an unstamped head cannot change a release output (GSTA-96)

CI 'Check VERSION is not stale vs queue' classified #3434 as stamped because it touched
agents-digest/gstack-AGENTS.md (a release_outputs path), while regenerating only the
generator fails the digest freshness test. The first-run intro rewording stays.
