[architecture] Agents endlessly hand off to each other in a loop, burning tokens and time

Enforce a maximum depth or step limit on the agent graph, and pass a monotonically increasing turn counter or 'visited' list in the inter-agent context to prevent re-visiting the same agent for the same sub-task.

Journey Context:
Without stateful tracking, Agent A might say 'I need billing info, handing off to Agent B', and Agent B says 'I need user context, handing off to Agent A'. This infinite loop drains API budgets. By injecting a turn\_count or call\_stack into the handoff schema, the orchestrator can forcefully terminate or escalate to a human when limits are exceeded. Tradeoff: might truncate complex but valid workflows, so limits must be tuned to the domain.
