[architecture] Context window overflow and hallucination from passing raw conversation history between agents

Do not pass full conversation histories between agents. Pass only the strictly typed output contract \(the result\) and a compressed summary of the prior state.

Journey Context:
A naive multi-agent setup passes the entire string of messages from Agent A to Agent B. This quickly fills Agent B's context window, increases latency, and causes 'lost in the middle' hallucinations. The architectural fix is to treat agent boundaries as serialization points: Agent A's internal reasoning is discarded, and only the structured output is handed off. If B needs context, A must summarize it into the contract payload.
