/**
 * Wraps the pull-based {@link NotificationHolderInterface} into a subscribe/unsubscribe API.
 *
 * The internal polling loop starts when the first listener subscribes and stops when the
 * last listener unsubscribes.  Re-subscribing after all listeners have been removed creates
 * a fresh {@link NotificationHolderInterface} and restarts the loop.
 *
 * @example
 * ```ts
 * const notifications = new WalletNotifications(wallet);
 *
 * const unsubscribe = notifications.subscribe((event) => {
 *   switch (event.tag) {
 *     case WalletNotification_Tags.MovementCreated:
 *       console.log('movement created', event.inner.movement);
 *       break;
 *     case WalletNotification_Tags.MovementUpdated:
 *       console.log('movement updated', event.inner.movement);
 *       break;
 *     case WalletNotification_Tags.ChannelLagging:
 *       console.log('channel lagging');
 *       break;
 *   }
 * });
 *
 * // later…
 * unsubscribe();
 * ```
