/**
 * Returns whether **adaptive video playback (ABR)** is currently enabled.
 *
 * This hook provides a reactive way to observe and respond to changes in the player’s
 * adaptive video mode — i.e., whether the player automatically selects the optimal
 * video rendition based on current network and performance conditions.
 *
 * **Disabling ABR:** There is no `disableAdaptiveVideo()`. To turn off adaptive playback,
 * select a specific rendition with `player.getTrackManager().setVideoRendition(rendition)`,
 * which **automatically disables** ABR. To re-enable ABR, call
 * `player.getTrackManager().enableAdaptiveVideo()`.
 *
 * ⚠️ Must be used within a {@link PlayerProvider} or
 * [AVPlayerViewControllerProvider](../../ios-avplayerviewcontroller-plugin-api/variables/AVPlayerViewControllerProvider.md) component.
 *
 * @returns `boolean` **true** if adaptive (ABR) mode is enabled, otherwise **false**.
 *
 * @example
 * ```tsx
 * import React from 'react';
 * import { View, Text, Button } from 'react-native';
 * import {
 *   usePlayer,
 *   useAdaptiveVideoEnabled,
 *   useVideoRenditions,
 * } from '@castlabs/react-native-prestoplay';
 *
 * export default function AdaptivePlaybackControl() {
 *   const player = usePlayer();
 *   const adaptiveEnabled = useAdaptiveVideoEnabled();
 *   const renditions = useVideoRenditions();
 *
 *   // Re-enable adaptive playback (ABR)
 *   const enableAdaptive = async () => {
 *     await player.getTrackManager().enableAdaptiveVideo();
 *   };
 *
 *   // Disable ABR by locking to the currently active rendition
 *   const lockToCurrentQuality = async () => {
 *     const current = renditions.find(r => r.active) ?? renditions[0];
 *     if (current) {
 *       await player.getTrackManager().setVideoRendition(current);
 *     }
 *   };
 *
 *   return (
 *     <View>
 *       <Text>Adaptive Playback: {adaptiveEnabled ? 'Enabled' : 'Disabled'}</Text>
 *       {adaptiveEnabled ? (
 *         <Button title="Lock to Current Quality" onPress={lockToCurrentQuality} />
 *       ) : (
 *         <Button title="Enable Adaptive Playback" onPress={enableAdaptive} />
 *       )}
 *     </View>
 *   );
 * }
