19.0.19

This release solves several issues that occurred with Angular 19.2, and it also solves issues with an entire class of npm packages using Singletons. For this, it delegates directly to the underlying bundler for chunk splitting. Hence, we don't need the transient flag anymore. transient deps will end up in their own bundles automatically when required (when used from more than one other dependencies). In this regards, Native Federation now behaves like Module Federation.
