[architecture] Passing entire conversation histories between agents blowing up context windows and cost

Summarize state into a structured handoff brief \(JSON object\) containing only necessary variables and a concise summary, rather than passing raw chat logs.

Journey Context:
Agents need context, but raw history is noisy and expensive. Token limits get hit quickly in multi-agent chains. Structured briefs force the extracting agent to distill signal from noise. Tradeoff: potential loss of subtle nuance, but massive gains in reliability, latency, and cost.
