Report #62346

[architecture] Multi-agent system hangs indefinitely because agents are waiting on resources held by each other

Implement timeout-based rollback for tool/resource acquisition and enforce a strict global ordering for acquiring shared resources in agent planning prompts.

Journey Context:
Classic distributed deadlock occurs when agents acquire tools or locks dynamically. If they don't follow a strict global ordering for acquiring resources, deadlocks occur \(Agent A waits for DB while holding File; Agent B waits for File while holding DB\). Since LLMs don't inherently know OS-level deadlock prevention, the orchestrator must enforce timeouts on tool usage and instruct agents to acquire resources in a predefined hierarchy, trading some concurrency for guaranteed progress.
