[research] Multi-agent handoffs lose context or route to the wrong agent

Implement trace-level evals that score the routing decision and context transfer at handoff boundaries, not just the final output. Validate that the receiving agent gets exactly the required schema and state.

Journey Context:
Developers often only evaluate the final output of a multi-agent pipeline. If Agent A hands off to Agent B with the wrong context, Agent B might hallucinate a correct-looking final answer by coincidence. Evaluating just the end state misses routing pathologies. By asserting on the intermediate handoff payload \(e.g., verifying the next\_agent and context variables\), you catch context loss early before it causes silent failures downstream.
