Module materializer 

State materialization — reconstruct current workflow state from events.

Current state = latest_snapshot.state + apply(events since snapshot)

Each NodeCompleted event carries a state_patch (a JSON merge patch, RFC 7396) that is applied in sequence to evolve the workflow’s current_state.
