Report #49506

[architecture] Infinite loop of agents handing off to each other

Implement a maximum handoff depth counter in the shared state and a fallback agent that catches tasks exceeding the limit.

Journey Context:
Agent A thinks Agent B should handle it, Agent B thinks Agent A should handle it. Because LLMs are non-deterministic, they can get stuck in a ping-pong loop. Without a hard limit on handoffs, the system runs forever, burning tokens. You must pass a turn\_counter or handoff\_depth in the shared state, and if it exceeds a threshold \(e.g., 3\), route to a termination or fallback agent.
