[architecture] Context window exhaustion from passing full conversation histories during agent handoffs

Implement context summarization or structured state transfer at handoff boundaries. Pass only the distilled schema-compliant result and the immediate necessary context, dropping the raw conversational turns of the previous agent.

Journey Context:
To maintain continuity, developers pass the entire messages array from Agent A to Agent B. In a deep chain, this exceeds the context window and inflates costs. Agent B usually only needs the final answer from Agent A. Tradeoff: summarization loses fine-grained details, but it is the only way to scale multi-agent chains beyond 2-3 steps.
