[research] Evaluating only final agent output, missing context loss in multi-agent handoffs

Inject eval checks at every agent-to-agent handoff point in the trace to verify context preservation and intent alignment before the next agent acts.

Journey Context:
In multi-agent systems \(e.g., planner -> coder -> reviewer\), the final output might fail because the planner's intent was lost when passing to the coder. If you only eval the final code, you cannot pinpoint the failure. You need trace-level evals that score the intermediate handoff payloads \(e.g., 'Does the coder's prompt contain all constraints from the planner?'\).
