This commit introduces the new hybrid rendering API for Angular's Server-Side Rendering (SSR). The API aims to enhance the flexibility of SSR as discussed in https://github.com/angular/angular/discussions/56785 - This API is currently not accessible. - Additional work is required in the Angular CLI to: - Wire up the manifest. - Integrate other necessary components.
