Release

Post it now: whatever of this post is still waiting falls due at once.

Released, not just re-dated. A delivery due now still waits out the gap after its network's last post, goes behind anything older that is also due, and — if the detector wrote it — waits for auto-posting to be turned back on. released_at is how the claim knows a person asked for this one (gcg.social.queue.claim says what that lets through, and what not).

The worker takes it on its next pass, worker.PUBLISH_EVERY apart. Only what is still scheduled moves: a send in flight cannot be hurried, and what went out, failed or was cancelled stays as it is.
