Module data 

The Arora data interface.

The shared, path-keyed blackboard that the HAL, the bridge, and execution engines (behavior tree, modules) all agree on:

• the vocabulary — Key, State, StateChange — lifted from studio-bridge so every consumer shares one definition;
• the DataStore trait (a shared, observable store) with a Slot direct-handle and a lean Subscription change feed.

The canonical lean implementation lives in the arora-simple-data-store crate (a simple hashmap store); richer backends can implement DataStore too.
