[research] Context lost or mutated during agent handoffs

Inject a structured 'handoff payload' eval step. Assert that the receiving agent's initial prompt contains all required keys from the sending agent's final output, and that no hallucinated keys are present.

Journey Context:
Agents passing tasks often drop critical context or hallucinate new state because the LLM summarizes the handoff instead of strictly passing the schema. Just checking if the second agent completes its task is too loose; it might re-fetch data the first agent already retrieved. Strict schema validation at the handoff boundary prevents compounding errors.
