[architecture] Context window overflow and hallucination from passing full chat history between agents

Implement a 'summarization \+ schema' handoff protocol. The upstream agent outputs a strictly typed payload \(the result\) and a compressed summary of the trajectory, rather than the raw message history.

Journey Context:
It is tempting to just pass the entire messages array from Agent A to Agent B so B has 'full context'. This quickly hits token limits, increases latency, and causes B to get confused by A's scratchpad or internal reasoning tokens. The alternative is strict encapsulation: agents should act like microservices, not monologues. They expose an API \(schema contract\) and a summary, not their internal logs. Tradeoff: B loses fine-grained details of A's reasoning, but gains focus, efficiency, and reduced hallucination risk.
