BREAKING CHANGE(smartproxy/configuration): Migrate SmartProxy to a fully unified route‐based configuration by removing legacy domain-based settings and conversion code. CertProvisioner, NetworkProxyBridge, and RouteManager now use IRouteConfig exclusively, and related legacy interfaces and files have been removed.
