LiveObjects comes to Java: navigating shared state with the path API

What this post added

Introduces a Java SDK for LiveObjects, specifically the Path API, which allows developers to navigate and manage shared state within an object tree using path references instead of direct object instances. This simplifies handling state changes, conflict resolution, and reconnection by providing stable references that outlive specific object instances. The API supports inferring data types at the point of use and provides methods for reading and writing data through these paths, enabling use cases like live leaderboards, AI agent session state, and collaborative configuration panels.
