[research] Multi-agent handoffs lose context or hallucinate state

Implement trace-level evals that specifically assert the presence of required keys in the handoff payload, and use LLM-as-a-judge to verify the receiving agent's first action aligns with the sender's intent.

Journey Context:
End-to-end task evals miss \*where\* a multi-agent system failed. If Agent A hands off to Agent B but omits a critical variable, Agent B might hallucinate it or fail gracefully but incorrectly. You must evaluate the seams \(the handoff events\) by checking schema compliance and intent continuity, not just the final output.
