[synthesis] Multi-agent handoffs cause context bloat or critical detail loss leading to downstream agent failure

Implement a structured 'handoff document' pattern: a JSON schema that strictly defines what information must be passed between agents, forcing the sending agent to extract only the required fields and preventing the receiving agent from inheriting unnecessary conversational history.

Journey Context:
Naively passing messages between agents seems easiest but quickly hits context limits and poisons the downstream agent with irrelevant reasoning traces. Summarization is too lossy and often drops the exact detail needed for the next step. A structured handoff schema enforces a clean interface contract, similar to microservice APIs, ensuring high-signal transfer without the bloat.
