[research] Multi-agent handoffs fail silently because the receiving agent gets malformed context from the sender

Implement trace-level evals that assert the schema and semantic completeness of the handoff payload between agents, not just the final output of the last agent.

Journey Context:
In multi-agent systems, developers often only evaluate the final output. If Agent A passes unstructured or missing context to Agent B, Agent B might hallucinate a plausible-sounding but incorrect final answer. You must evaluate the intermediate handoffs. Use LLM-as-a-judge or schema validators at the boundary between agents to catch context degradation early.
