[architecture] Context window overflow and degraded reasoning from syncing full conversation histories between agents

Implement diff-based synchronization or state summarization. Pass only the structured delta \(what changed\) or a compressed summary of the previous agent's actions, never the raw transcript.

Journey Context:
To give an agent context, developers often dump the entire history of the previous agent into the next agent's prompt. This causes quadratic attention scaling, increases latency, and triggers the 'lost in the middle' phenomenon where the LLM ignores crucial instructions buried in the context. The solution is to treat inter-agent communication like an API payload: send the updated state object, not the debug log. If narrative context is needed, use a dedicated summarization step to compress the history before the handoff.
