 * ### Custom Health Checks
 * **Example:** Flag a failing instance for replacement
 * ```typescript
 * // init — bind the operation to the group
 * const setInstanceHealth = yield* AWS.AutoScaling.SetInstanceHealth(group);
 *
 * // runtime — mark the instance unhealthy so the group replaces it
 * yield* setInstanceHealth({
 *   InstanceId: instanceId,
 *   HealthStatus: "Unhealthy",
 * });
