[research] Multi-agent handoffs lose critical context causing downstream hallucinations

Inject a structured handoff summary payload into the trace span attributes and enforce a schema check on it before the receiving agent starts execution.

Journey Context:
When Agent A passes control to Agent B, developers often just pass the raw chat history. This bloats the context window and B often misses A's core intent. By forcing A to generate a structured handoff summary \(JSON\) and validating it, you create a traceable, evaluable artifact. If B fails, you can instantly eval whether A's summary was deficient or B misunderstood it.
