State change event protocol for Durable Streams

// `@durable-streams/state/db`: the full surface, including the reactive,
// TanStack DB-backed StreamDB layer. Importing this entry pulls in @tanstack/db,
// which is a peer dependency — consumers using this subpath must install it.
//
// It is a strict superset of the db-free main entry (`@durable-streams/state`),
// so code that uses both `createStateSchema` and `createStreamDB` can import
// everything from here.
