Report #29975

[frontier] Passing full conversation history between agents causes exponential context growth

Implement State Summarization at Handoff. When Agent A hands off to Agent B, pass only the structured output \(deliverable\) and a one-paragraph summary of intent, not the raw chat logs.

Journey Context:
Transparency \(sharing everything\) is computationally expensive and confusing. Agents get distracted by irrelevant back-and-forth. The Information Hiding principle from software engineering applies to agents: share only what the interface contract requires.
