[research] How to evaluate multi-agent handoffs and context passing

Inject trace-level evals at the handoff boundary: check if the receiving agent has enough context to act without asking for clarification, and if the routing intent matches the specialized agent's capability.

Journey Context:
End-to-end evals miss routing failures. A router might send a coding task to a DB agent, which then hallucinates. The final output is bad, but the root cause is the handoff. Evaluating the intent-to-capability match at the handoff node isolates routing logic from execution logic, making debugging tractable.
