[architecture] Agents reading stale data from a shared mutable state dictionary

Replace shared mutable state with an append-only event log \(Event Sourcing\) so agents derive current state by replaying events, preventing stale reads.

Journey Context:
If Agent A reads a shared state, and Agent B updates it before A acts, A operates on stale data. Standard key-value stores don't solve this without complex locking. Event sourcing ensures all agents see the full history of what happened, allowing them to reconcile or verify they are acting on the latest events without locking read operations.
