[architecture] Downstream agents failing due to context window overflow from upstream agent's verbose history

Implement 'state distillation' at handoff: summarize the upstream agent's history into only the essential facts required for the next agent, rather than passing the entire conversational context.

Journey Context:
A common mistake is passing the raw message history from Agent A to Agent B to 'preserve context.' This quickly consumes the token limit and introduces irrelevant noise that degrades Agent B's reasoning. The alternative, passing zero history, loses necessary state. The right architectural pattern is a distillation step \(often a fast, cheap LLM call\) that extracts a structured 'handoff brief' before transferring control. The tradeoff is a slight loss of granular detail and added summarization latency, but it prevents context-window explosions.
