[architecture] Agents bouncing a task back and forth infinitely because neither takes ownership

Implement a hard maximum handoff depth limit and require the receiving agent to explicitly accept or reject a task with a reason, preventing automatic re-delegation to the sender.

Journey Context:
When Agent A delegates to Agent B, and B lacks the context or capability, it often defaults to delegating back to A. Without a circuit breaker, this creates an infinite loop of handoffs, burning tokens and time. Setting a max\_depth \(similar to graph recursion limits\) forces the system to fail gracefully or escalate to a supervisor, mirroring call stack limits in traditional software.
