[architecture] Agents deadlock because each holds one resource while waiting for another

Impose a global total order on lockable resources and acquire locks in ascending order. Combine with lease timeouts so a crashed or stalled agent cannot hold a lock forever.

Journey Context:
Deadlocks happen when agents acquire shared resources in inconsistent orders. The resource-hierarchy solution comes from Dijkstra's dining-philosophers analysis: if every agent picks up forks in the same order, circular wait is impossible. Timeouts alone are not enough because they can livelock; ordering alone is not enough because a crash can orphan a lock. You need both.
