ng19 Standalone imports are not recognized unless "standalone: true" is specified.

[emonney]

In angular 19 standalone imports are the default so setting "standalone: true" in component declaration is not needed/recommended.
However VisualStudio does not recognize the imports and shows this error: 'imports' is only valid on a component that is standalone.(-992010)
Also everything that depends on those imports also shows errors. The template and code editors are riddled with false positive errors.

Update the language service to recognize that angular 19+ components are standalone by default and don't need the extra "standalone: true" decoration.

Can you confirm, e.g. by looking at the "Angular Language Service Extension" output in the Output window, that the version of @angular/language-server being used is 19 or higher?

Otherwise it could seem related to #78 and version 17 of the language server being bundled with the extension, and a local version only being used if installed directly into the solution directory.

I tried updating to version 19.0.3 of @angular/language-server, but the issue of not taking into consideration the new default of implying standalone: true when not specifying standalone persists. and now a component with standalone unspecified is recognized as being standalone.

(A similar issue has been reported for @angular/language-server (angular/vscode-ng-language-service#2130), although I believe it might be unrelated.)
