[research] Context mutation or loss during multi-agent handoffs goes undetected until final output fails

Inject trace IDs and implement per-handoff evals that check the output schema and semantic intent of the passing agent before the receiving agent starts. Use a supervisor step to validate the handoff payload.

Journey Context:
In multi-agent systems, Agent A passes context to Agent B. If Agent A summarizes poorly or drops a key variable, Agent B operates on bad data, leading to a final failure that looks like Agent B's fault. Root-causing this post-mortem is extremely difficult without trace-level evals at the handoff boundary. Validating the intermediate state prevents cascading errors.
