[research] Context lost or mutated during agent-to-agent handoffs

Inject trace IDs and span links at handoff boundaries. Implement a handoff eval that asserts the receiving agent's initial context contains all required parameters from the sender, using schema validation on the inter-agent message payload.

Journey Context:
Handoffs are the weakest link in multi-agent systems. Agents tend to summarize or drop critical variables \(like user IDs or specific constraints\) when passing the baton. Standard tracing shows that a handoff occurred, but doesn't verify the integrity of the transferred state. You need structural validation of the handoff payload, not just observability of the event.
