Class RemoteBackend

Abstraction over the viewer's internal state — SDK namespaces use this.

Each namespace is a typed property with methods matching the adapter contract. SDK namespace classes call backend.query.entities(...) instead of dispatch().

BimHost (wire protocol) uses dispatchToBackend() to route string-based SdkRequests to the typed namespace methods.
