useChangesTrackerStore

const useChangesTrackerStore: UseBoundStore<WithDevtools<StoreApi<ChangesTrackerStore>>>

Zustand store that emits a tick every time a tracked diagram change is about to happen. Subscribe with useChangesTrackerStore((s) => s.lastChangeName) (or other fields) to react to changes — useful for undo/redo plugins, autosave, audit logging, and so on.

State shape: { lastChangeName, lastChangeParams, lastChangeTimestamp } — the timestamp is the cheapest field to subscribe to when you only care about “something changed”.
