Report #4771

[architecture] Syncing entire conversation histories between agents causing context window overflow and attention dilution

Pass only the exact structured state delta required for the next agent to operate. Summarize the outcome of the previous agent into a concise JSON object before handing off.

Journey Context:
Naively passing the full messages array to the next agent seems like a good idea for preserving context, but LLMs suffer from lost-in-the-middle syndrome and strict context limits. Bloated histories increase latency, cost, and hallucination rates. State should be distilled, not bulk-copied.
