[architecture] Agents operating on stale state because they only received a snapshot at handoff

Use a shared, append-only state graph \(like a blackboard architecture\) that all agents read from and append to, rather than passing entire state copies via messages.

Journey Context:
Passing the full state as a message payload works for 2 agents but scales poorly. As agents mutate state, others hold stale copies, leading to divergent realities \(e.g., Agent A adds a dependency, Agent B writes code without it\). Passing the whole state every time blows up the context window. The Blackboard pattern allows agents to read only the diff or relevant sections of the global state and append their updates. The tradeoff is the need for a centralized state store and schema versioning, but it ensures all agents operate on the same ground truth.
