QueuedAgent

An agent an AgentWorker can run queued entries for (Stage 5 W2, design 4.56): an Agent, whose queued starts are QueuedInput.query's AgentInput, or a bound TypedAgent[I, O], whose queued starts are QueuedInput.typed's I, rendered as its first user message as BoundAgent.run renders it. Entries name it by id. Its runtime must be over the worker's store.
