[architecture] Infinite routing loops between agents passing responsibility back and forth

Embed a monotonically decreasing depth or hop\_count integer in the inter-agent message contract, and terminate the chain with an error or HITL escalation if it reaches zero.

Journey Context:
In multi-agent systems, agents often have overlapping capabilities. Agent A thinks Agent B should handle it, Agent B thinks Agent A should. Without a TTL or hop count in the message header, this loops infinitely, draining tokens and API credits. The tradeoff is that a low depth might prematurely terminate a genuinely complex but valid chain, so the depth limit must be tuned to the specific workflow's maximum expected depth.
