[architecture] Agents bouncing a task back and forth indefinitely in an infinite handoff loop

Implement a global handoff depth counter in the shared state, and trigger a fallback or human escalation when the limit is exceeded.

Journey Context:
LLMs often fail silently by routing a task back to the previous agent \(I cannot process this, returning to sender\). Without a circuit breaker, this loop runs indefinitely, burning tokens. A depth counter acts as a failsafe, forcing the system to admit failure gracefully rather than looping forever.
