[architecture] Multi-agent systems stuck in infinite handoff loops \(Agent A routes to B, B routes back to A\)

Implement a global handoff counter or depth limit in the orchestrator state. If an agent pair exceeds the threshold, force a termination or escalate to a fallback agent.

Journey Context:
When agents use confidence-aware routing or conditional handoffs, they often encounter oscillation: Agent A thinks Agent B should handle it, Agent B disagrees and hands it back. Without a circuit breaker, this loops infinitely, burning tokens. A simple monotonically increasing handoff counter in the shared state, checked by the orchestrator before each routing decision, is the most robust architectural safeguard against this failure mode.
