[architecture] Agents losing track of shared progress or reading stale state, resulting in duplicated work

Implement a centralized, append-only state store \(Blackboard architecture\) with structured keys, rather than passing full state histories in message payloads.

Journey Context:
Passing the entire conversation/state history between agents causes context window bloat and high latency. If agents just read/write to a shared DB, they can pull only the specific state they need. However, naive shared state leads to race conditions. An append-only event log \(Blackboard pattern\) allows agents to read the latest state without overwriting each other's contributions. Tradeoff: requires agents to know the schema of the blackboard.
