 * ### Observing Instances
 * **Example:** Check the instance's status checks
 * ```typescript
 * // init — bind the operation to the instance
 * const describeStatus = yield* AWS.EC2.DescribeInstanceStatus(instance);
 *
 * // runtime — read status checks (even while stopped)
 * const result = yield* describeStatus({ IncludeAllInstances: true });
 * console.log(result.InstanceStatuses?.[0]?.InstanceStatus?.Status);
 * ```
