Turn a waiting item into a request made by hand, so that it is worked as soon as a submission slot is free.

Whatever was holding the item no longer does: the minimum interval between verdicts, the daily limit, a retry delay after a failed attempt, or a verdict being formed for another host in the same situation. Its attempt count starts again, and it moves to the front of the queue. When it runs it is treated as any request made by hand, as described for beginHostTriage: a host with something alerting is submitted to the AI provider whatever the automatic checks would have decided. An item that would only have taken up another host's verdict becomes a full triage of its host.

A pause after the AI provider rate-limits a submission applies to the whole queue and is not lifted by this request; the item runs when the pause ends.
