[research] Agent handoffs losing context or failing silently without final output degradation

Implement trace-level evaluations at every agent handoff boundary, validating that the passed context matches the receiving agent's expected schema and intent, not just evaluating the final output.

Journey Context:
Final-output evals miss the 'telephone game' degradation in multi-agent systems. A slight context drop in step 2 might not break the final output immediately but causes brittle behavior later. Trace-level evals catch these silent context mutations early, though they require instrumenting the orchestration layer to emit structured events at handoffs.
