[architecture] Passing entire conversation histories between agents, blowing up context windows and losing focus

Summarize state upon handoff; pass only the structured intent, required variables, and a brief summary rather than the full transcript.

Journey Context:
Naive multi-agent setups pass the whole chat history to the next agent. This rapidly hits token limits, increases latency, and degrades the receiving agent's reasoning due to irrelevant noise. The handoff boundary must act as a filter: extract only the structured data and a compressed summary needed for the next step, shedding the conversational baggage.
