[research] Context lost or malformed during multi-agent handoffs

Implement trace-level evals by injecting a synthetic 'handoff validation' step. Use OpenTelemetry spans with parent\_id linking, and assert that the payload received by Agent B matches the payload dispatched by Agent A.

Journey Context:
Agents passing tasks often drop keys or misinterpret JSON structures. Standard logging misses the state transition. By modeling handoffs as distributed trace spans, you can visualize the exact context mutation and write assertions on the span attributes at the boundary, treating the handoff as a contract.
