[architecture] Two agents continuously delegate tasks back and forth in an infinite loop

Implement a hop-count or TTL \(Time-To-Live\) counter in the shared context that decrements on every agent handoff; abort the chain if it hits zero.

Journey Context:
Unlike traditional code with explicit termination conditions, LLM agents can get stuck in conversational loops where they lack the context to break out. Agent A delegates to B, B does the work but leaves the overall goal unresolved, so B delegates back to A. Without a mechanical circuit breaker, this runs until token limits are hit, costing money and time. A simple max\_hops counter in the state payload provides a hard stop. The tradeoff is that you might abort a genuinely complex task that requires many steps, so the TTL must be tuned to the workflow's upper bound.
