[architecture] Context window overflow and hallucination caused by passing full conversational history between agents

Implement a 'context contract' where agents do not share raw chat history, but instead pass strictly typed, summarized state objects \(DTOs\) across boundaries.

Journey Context:
Naive multi-agent setups pass the entire string of messages from Agent A to Agent B. This quickly exhausts context limits and introduces irrelevant noise, causing B to hallucinate or lose focus. The architectural fix is to treat agent boundaries like microservice boundaries: pass Data Transfer Objects \(DTOs\) or structured state summaries, not raw logs. The tradeoff is the loss of subtle context that might exist in the full history, but the gain in reliability, cost reduction, and focus is essential for scalable multi-agent systems.
