/**
 * Check if a slot renders meaningful content.
 *
 * `$slots.foo` is truthy as soon as the parent declares `<template #foo>`,
 * even when that template renders nothing (e.g. via `v-if="false"`).
 * This helper invokes the slot function and walks the returned VNodes
 * to detect whether any real DOM or component will be produced.
 *
 * For scoped slots that require bindings, the function falls back to
 * a simple existence check since they cannot be safely invoked without
 * the expected arguments.
 *
 * @example
 * ```vue
 * <div v-if="hasSlotContent($slots.footer)">
 *   <slot name="footer" />
 * </div>
 * ```
