Subject: [PATCH] fix(build): register interceptor namespaces through the
 InterceptorsNamespaces property

- Set InterceptorsNamespaces instead of appending a second InterceptorsNamespaces entry to Features.
- The compiler keeps only the last entry, so the Features form dropped the SDK generators namespaces and, when a project listed its own, the generated one.
