[research] Multi-agent handoffs cause silent context loss or hallucinated state

Evaluate the handoff message explicitly using a schema validator or a dedicated LLM-judge before the receiving agent starts execution.

Journey Context:
Developers assume the orchestrator passes full state. In reality, agents summarize or drop critical variables during handoffs. Evaluating only the final output misses that the failure occurred at the routing layer. Trace-level evals at the handoff boundary catch this early.
