[architecture] Infinite handoff loops where agents bounce a task back and forth without resolution

Implement a hard maximum recursion depth or handoff counter in the orchestrator, and define an explicit fallback or escalation agent when the limit is reached.

Journey Context:
LLMs lack inherent self-correction boundaries. If Agent A delegates to Agent B, and Agent B delegates back to A, they loop indefinitely, burning tokens. Alternatives like 'let them argue' waste compute. The right call is a deterministic circuit breaker enforced by the orchestrator. Tradeoff: It might abort a legitimate multi-step reasoning chain, but preventing unbounded cost is a strict requirement for production systems.
