- Add SWQOS_ENDPOINTS_BLOCKRAZOR_GRPC with correct gRPC endpoints - Add Grpc variant to SwqosTransport enum - Add get_endpoint_with_transport() method for transport-aware endpoint selection - Change BlockRazor default: transport=None now uses gRPC (was HTTP) - Require explicit Some(SwqosTransport::Http) for HTTP fallback This fixes the issue where BlockRazor was incorrectly using HTTP endpoints when gRPC was intended. Users can now use gRPC by default or explicitly specify HTTP transport when needed. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
