 * ### Observing Scaling Activity
 * **Example:** List Recent Scaling Activities
 * ```typescript
 * // init — bind the operation to the scalable target
 * const describeScalingActivities =
 *   yield* AWS.ApplicationAutoScaling.DescribeScalingActivities(target);
 *
 * // runtime — page through the target's recent activities
 * const page = yield* describeScalingActivities({ MaxResults: 50 });
 * for (const activity of page.ScalingActivities ?? []) {
 *   yield* Effect.log(`${activity.StatusCode}: ${activity.Description}`);
 * }
 * ```
 *
 * **Example:** Include Not-Scaled Reasons
 * ```typescript
 * const page = yield* describeScalingActivities({
 *   IncludeNotScaledActivities: true,
 * });
 * ```
