[architecture] Context window overflow and cost explosion from passing full conversational history between agents

Implement a context contract at handoff where the outgoing agent summarizes its findings into a strictly bounded payload, and the orchestrator discards the raw history before invoking the next agent.

Journey Context:
A common anti-pattern is passing the entire chat history from one agent to the next to 'maintain context.' This quickly hits token limits, increases latency, and degrades performance due to lost-in-the-middle effects. The architectural fix is to treat agent boundaries as information dams. Only the structured output crosses the boundary. Tradeoff: Loss of subtle nuance from the raw history, but guarantees predictable token usage and focused downstream execution.
