Define PubSub and Subscription interfaces in the core via package with a vianats sub-package providing the embedded NATS + JetStream implementation. Expose c.Publish() and c.Subscribe() on Context with automatic subscription cleanup on session close. Refactor the NATS chatroom example to use the built-in methods instead of manual subscription tracking.
