[architecture] Infinite handoff loops between agents

Implement a deterministic maximum handoff depth counter and a fallback catch-all agent that takes ownership when the limit is reached, breaking the cycle.

Journey Context:
LLMs are bad at recognizing the limits of their own or other agents' capabilities. Agent A thinks Agent B should handle it; Agent B disagrees and hands back to A. Without a circuit breaker, this loops infinitely, burning tokens. Alternatives like prompt-based warnings \('do not loop'\) are unreliable. A programmatic depth counter is a simple, deterministic guardrail against non-deterministic routing failures.
