// Main entry: the db-free surface of the state protocol.
//
// Everything exported here works without @tanstack/db installed — defining
// schemas, constructing/validating change events, and materializing state
// in-memory. The reactive, TanStack DB-backed StreamDB layer (createStreamDB,
// live queries, optimistic actions) lives under the `@durable-streams/state/db`
// subpath, which carries the `@tanstack/db` peer dependency.
