[synthesis] Multi-agent handoff loses the original user intent and accumulates conversational drift

When handing off between agents, inject a compressed 'intent summary' and a 'constraint checklist' into the receiving agent's system prompt, rather than just passing the raw chat history.

Journey Context:
Passing full chat history between agents seems like the most faithful way to preserve context. However, LLMs suffer from 'lost in the middle' and recency bias. In multi-agent setups, the receiving agent focuses on the last few messages \(often just the handoff trigger\), completely ignoring the original constraints established 10 turns ago. This leads to agents solving the wrong problem or violating early constraints. Compressing the history into an explicit intent summary and checklist forces the receiving agent to align with the original goal, breaking the drift cascade.
