Linked signal fixes

[crutchcorn]

While building TanStack Store, I noticed that both it and this package have issues reading input.required logic from a selector:

@Component({
    selector: 'app-count-and-add',
    standalone: true,
    template: `
      <button aria-label="Increment value" (click)="dispatch(increment())">
        Increment
      </button>
      <p>Count: {{ count() }}</p>
    `,
  })
  class CountAndAdd {
    dispatch = injectDispatch();
    increment = counterSlice.actions.increment;
    addBy = input.required<number>();
    count = injectSelector((state: any) => state.counter.value + this.addBy());
  }

However, the fix to this solution is to use linkedSignal to sidestep the timings of input.required, so we bumped the major to 2.x and only support Angular 19+
