/**
 * Runtime binding for `ecs:RunTask`.
 *
 * Bind this operation to a `Cluster` and `Task` inside a function runtime to
 * get a callable that starts a Fargate task from the bound task
 * definition. The cluster and task definition ARNs are injected automatically;
 * the host is granted `ecs:RunTask` on the task definition plus `iam:PassRole`
 * on the task and execution roles.
 * ### Running Tasks
 * **Example:** Launch a Fargate Task from a handler
 * ```typescript
 * const api = yield* AWS.Lambda.Function(
 *   "Api",
 *   { main: import.meta.url, functionUrl: true },
 *   Effect.gen(function* () {
 *     // init: bind the launch (IAM grants happen here)
 *     const runTask = yield* AWS.ECS.RunTask(cluster, task);
 *
 *     return {
 *       fetch: Effect.gen(function* () {
 *         // runtime: launch a task per request
 *         const response = yield* runTask({
 *           launchType: "FARGATE",
 *           networkConfiguration: {
 *             awsvpcConfiguration: {
 *               subnets: [subnetId],
 *               assignPublicIp: "ENABLED",
 *             },
 *           },
 *         });
 *         return yield* HttpServerResponse.json({
 *           taskArn: response.tasks?.[0]?.taskArn,
 *         });
 *       }),
 *     };
 *   }),
 * );
 * ```
