[architecture] Context window exhaustion and performance degradation from passing raw conversational history between agents

Implement context distillation at handoff. The outgoing agent must summarize its findings and actions into a strictly bounded handoff payload, rather than passing the raw transcript to the next agent.

Journey Context:
It is tempting to pass full history for maximum context, but LLMs suffer from lost-in-the-middle and distraction. Summarization loses granular details but preserves the exact signal needed for the next step. Tradeoff: Extra LLM call for summarization vs. cost/accuracy degradation from massive context.
