Angular 21 - addon-vitest support

[kyleryanbanks]

Is your feature request related to a problem? Please describe.

With Angular 21 now using Vitest as its default test runner and using vite for the dev servers, will we be able to get official support for Angular in 'addon-vitest'?

Describe the solution you'd like

I would like to not have to use workarounds (shoutouts to the AnalogJS team) and be able to utilize the vitest tooling for testing my Angular applications in Storybook, as well as in my CI.

Describe alternatives you've considered

@brandonroberts and the AnalogJS team have provided some fantastic workarounds to bridge the gap while Angular was lacking official Vite and Vitest support, but with them become integrated framework tooling, I would like to remove as much custom setup as possible.

The older test runner solution was a fine second option, as well, but the lack of visual testing and the lack of Jest in the rest of my tooling stack post v21 is definitely a pain point now.

Are you able to assist to bring the feature to reality?

yes, I can
