[research] Agent loses critical context or task state during multi-agent handoffs

Implement trace-level evals by asserting the presence of required state variables in the handoff span's attributes. Use a deterministic context checklist eval that runs at the boundary of every agent transfer to verify required keys are carried over.

Journey Context:
When Agent A hands off to Agent B, developers often rely on the LLM to summarize the state into the prompt. This is lossy. Observability tools show the handoff occurred, but not if the state survived intact. By attaching structured state \(JSON\) to the trace span and running a programmatic eval on that span at handoff-time, you deterministically catch context drift before Agent B starts its work, avoiding expensive multi-step failures down the line.
