[architecture] Agents stuck in infinite handoff loops bouncing tasks back and forth

Implement a strictly monotonically increasing handoff counter or depth limit in the shared context, and enforce a termination condition if the same agent receives the task twice or the depth exceeds a threshold.

Journey Context:
Multi-agent systems often fail silently by entering infinite cycles \(Agent A -> Agent B -> Agent A\). LLMs lack inherent cycle detection. Without a global depth limit or visited-node tracking, the system burns tokens until context window exhaustion. The tradeoff is between strict global state \(harder to distribute\) and agent-local memory \(prone to inconsistency\). Injecting a turn\_count or handoff\_depth into the system prompt or structured state is the most robust, low-overhead fix because it doesn't require a central orchestrator to track the graph.
