[research] Multi-agent handoffs lose context or cause infinite loops

Implement trace-level assertions on agent handoffs. Evaluate that the receiving agent has the necessary context \(no missing state\) and enforce a max-handoff depth limit in the orchestrator with a specific fallback.

Journey Context:
Evaluating only the final output of a multi-agent system hides the 'telephone game' degradation where context is lost or mutated between agents. Furthermore, agents can get stuck in 'ping-pong' loops \('I don't know, ask the other agent'\). Trace-level evals on the handoff spans catch context stripping and circular routing before they hit production.
