/**
 * Directive for observing element intersection with viewport or ancestor elements using IntersectionObserver.
 * The `v-intersection` directive allows you to respond to changes in an element's visibility.
 *
 * Example usage:
 *     <div v-intersection="handleIntersection">Observable content</div>
 *     <div v-intersection="handleIntersection" :options.intersection="{threshold: 0.5}">Observable content</div>
 *
 * The handler receives IntersectionObserverEntry array as the first argument and $ctx as the second:
 *     handleIntersection(entries, $ctx) {
 *       const entry = entries[0];
 *       if (entry.isIntersecting) {
 *         console.log('Element is visible!');
 *       }
 *     }
 *
 * Options can be provided via :options or :options.intersection attribute:
 *     :options="{root: null, threshold: 0.5, rootMargin: '0px'}"
 *     :options.intersection="{root: null, threshold: 0.5, rootMargin: '0px'}"
 *
 * This directive is useful for lazy-loading, infinite scrolling, animation triggers,
 * and other features that depend on element visibility.
