[research] Multi-agent systems fail due to context loss during agent handoffs, but evals only check the final output

Implement trace-level evals specifically targeting the handoff boundaries. Verify that the receiving agent's initial prompt contains the exact, necessary state from the sender, and that no critical variables were dropped or fabricated during the transfer.

Journey Context:
Final-output evals hide handoff failures because subsequent agents might hallucinate workarounds or produce plausible but incorrect final answers. Handoffs are the integration points of agentic systems. Tracing must capture the exact payload transferred and evaluate it independently of the final outcome.
