+Resolve `TopicQuery` adapter via subclass-aware lookup. `TopicQuery` now assigns `static adapter = TopicQueryAdapter` so subclasses inherit a runtime value without per-class overrides, and `QueryClient.getAdapter()` falls back to an `instanceof` scan over registered adapters before auto-instantiating, so an abstract base on a query resolves to the consumer-registered concrete subclass.
