[architecture] Context window overflow and agent confusion in never-ending multi-agent group chats

Implement a strict message trimming or summarization strategy, bounding the historical context passed to any single agent.

Journey Context:
A common failure mode in group chat architectures \(like round-robin agent discussions\) is passing the entire, ever-growing transcript to every agent. This quickly exceeds token limits, degrades the LLM's ability to follow instructions \(lost in the middle\), and increases latency and cost. The fix is to treat the message history as a sliding window or use a summarization node to compact the context before it grows unbounded.
