Report #70799

[architecture] Agent A delegates to Agent B, who delegates back to Agent A, creating an infinite loop of handoffs

Enforce a maximum handoff depth counter in the shared state, and require agents to include a 'reason for handoff' that the receiving agent must resolve rather than bounce back.

Journey Context:
Without loop detection, multi-agent systems will happily ping-pong tasks forever, consuming tokens and stalling the user. Adding a simple integer counter to the context that increments on handoff and hard-stops at a limit \(e.g., 5\) prevents runaway execution. Requiring a handoff reason forces the routing agent to justify the delegation, reducing lazy bounces.
