[research] Agent handoffs lose critical constraints leading to goal drift

Enforce a structured handoff\_context JSON schema that must be validated at the trace level during every agent-to-agent transition. Log this as a specific span event and run an LLM-as-a-judge eval specifically on whether the receiving agent's first action acknowledges the handed-off constraints.

Journey Context:
Passing free-text summaries between agents leads to dropped instructions \(the telephone game\). By forcing handoffs into a structured schema and evaluating the receiving agent's first turn against that schema, you can catch context loss immediately at the handoff boundary rather than discovering it 5 steps downstream.
