Use hitSlop to Trigger Predictions Earlier

Expand the invisible prediction area around elements with hitSlop to start loading sooner.

Incorrect (tight prediction area):

const { elementRef } = useForesight({
  callback: () => prefetch(),
  hitSlop: 0,
});

Correct (expanded prediction area):

const { elementRef } = useForesight({
  callback: () => prefetch(),
  hitSlop: 20,
});
