[architecture] Agents handing off to each other in an infinite loop

Implement a hard maximum handoff depth counter and a fallback resolver agent or human-escalation tool that breaks the cycle.

Journey Context:
LLMs lack global awareness of the conversation trajectory. If Agent A thinks Agent B should handle it, and B thinks A should, they loop infinitely. This is the multi-agent equivalent of an infinite redirect. Developers often assume the LLM will 'figure it out' based on prompt engineering, but without a programmatic circuit breaker, loops are guaranteed under edge cases. Tradeoff: Hard limits might prematurely cut off complex but valid workflows, but this is strictly necessary to prevent runaway token consumption and system freezes.
