[architecture] Passing full conversational history between agents causes context window exhaustion and degrades reasoning

Implement state compression at handoff boundaries: the outgoing agent must summarize its findings into a strictly bounded schema, discarding raw context before transferring control.

Journey Context:
Developers often pass the full messages array from Agent A to Agent B to 'maintain context.' This is an anti-pattern. LLMs suffer from lost-in-the-middle and distraction when context is bloated. Worse, passing raw history forwards propagates injection risks. The handoff should act as a firewall, extracting only the validated, necessary signals. Tradeoff: Loss of fine-grained details from early steps, but maintains the reasoning fidelity of downstream agents.
