Holds `Resource::KnowledgeTree` (capacity 1), so two pulls never overlap on the working tree; each trigger queues its own pass, which waits for the resource if one is already live.

 | `WantedPull`         | pull of the agent set the swarm controller declares for this hive (`wanted::pull`), converging the agents it names. Runs at boot, waiting up to a minute in total for the queue connection, and again after every attach of the wanted-state watch (which retries with a backoff when the attach fails or the stream ends); the deploy event (`swarm_status`) and the watch are the fast path, this repairs a missed one. A first deploy already queued or running for an agent isn't queued again. Agentless |
