[research] Agent handoffs lose context or hallucinate state

Implement trace-level evaluations at every agent-to-agent handoff, validating that the passed context matches the receiving agent's schema and contains no dropped or hallucinated keys.

Journey Context:
Developers often only evaluate the final output of a multi-agent system. If Agent A passes a JSON payload to Agent B, and B silently fails or hallucinates missing fields, the final output might look okay by luck or be subtly wrong. Evaluating intermediate traces catches context drift early before it compounds into catastrophic failure.
