/**
 * A hook for tracking hover state of an element.
 *
 * This hook uses use to ensure the hover state is always
 * represented as an observable, providing a consistent interface for
 * reactive state management.
 *
 * @template T - The type of the element
 * @param elementRef - Reference to the element to track hover state for
 * @returns An observable boolean representing the hover state
 *
 * @example
 * ```tsx
 * const elementRef = useRef<HTMLDivElement>(null)
 * const isHovered = useHover(elementRef)
 *
 * return (
 *   <div ref={elementRef}>
 *     {() => $$(isHovered) ? 'Hovered!' : 'Not hovered'}
 *   </div>
 * )
 * ```
 *
 * @see {@link https://github.com/vobyjs/woby|Woby documentation} for more information about observables
