[Bug]: Support of default Angular's inputs

Describe the bug

I just updated to the latest Angular (18.2.9) and Storybook (8.3.6) and was surprised to find that it doesn't support signals

I found a lot of discussions, but they all talk about input and output signals. I'm talking about a simple signal(...)

I found this and this. And I even see that you supported model(). But I don't understand why regular singal(...) is not supported?

Storybook has always allowed you to work with component fields without requiring you to make them inputs. this makes sense because public fields are what html uses. But inputs are a contract with the outside world.

Reproduction steps

example: https://stackblitz.com/edit/github-mbwd5e-mebzvr?file=src%2Fapp%2Fsignal-ex%2Fsignal-ex.stories.ts

let's say I have a component with a field. this field can be updated asynchronously. Previously I had to use BehaviorSubject for this and I could override the value from Storybook. now I want to use signal(). Storybook does not work with signal, but it works with model

@Component({
  selector: 'signal-ex',
  standalone: true,
  imports: [CommonModule],
  template: `Field: {{ field }} <br> Signal: {{ signalField() }} <br> Model: {{ modelField() }}`,
  styleUrls: [],
})
export class SignalExComponent {
  field = false;     // <- we can't use fields with ChangeDetection.OnPush
  field$ = new BehaviorSubject<boolean>(false);
  fieldSignal = signal(false);
  fieldModel = model(false);

  toggle() {
    this.field = true;
    this.field$.next(true);
    this.fieldSignal.set(true);
    this.fieldModel.set(true);
  }
}

story:

const meta: Meta<SignalExComponent> = {
  component: SignalExComponent,
  tags: ['autodocs'],
};

export default meta;
type Story = StoryObj<SignalExComponent>;

export const Primary: Story = {
  args: {
    field: true,
    field$: new BehaviorSubject<boolean>(true),
    fieldSignal: true as any,    // <- doesn't work
    fieldModel: true,
  },
};
