[research] Evaluating multi-agent handoffs without just checking the final output

Implement trace-level evals that score the context payload passed between agents at the handoff boundary, checking for information loss or hallucination, rather than only evaluating the final response.

Journey Context:
Final-output evals miss the 'telephone game' degradation in multi-agent systems. An agent can produce a correct final answer while relying on flawed intermediate reasoning passed from another agent. By evaluating the exact payload transferred at the handoff \(e.g., the context or next\_agent inputs\), you catch silent context drift before it compounds. OpenAI Swarm documentation explicitly highlights handoff mechanics as a core primitive, making the handoff boundary the natural eval checkpoint.
