The go-sdk v1.6.0 release no longer applies a default CrossOriginProtection when the field is nil in StreamableHTTPOptions, silently removing Origin header verification. Wrap the streamable handler with http.NewCrossOriginProtection().Handler(...) (the recommended replacement, since the SDK field is deprecated). Also regenerate gqlgen resolvers to track v0.17.90.
