/**
 * Runtime binding for `cloudwatch:GetMetricData` — run metric-math queries
 * over one or more metrics in a single call.
 *
 * Provide `CloudWatch.GetMetricDataHttp` on the hosting Lambda Function to
 * satisfy the requirement.
 * ### Querying Metrics
 * **Example:** Query the Last Hour of a Custom Metric
 * ```typescript
 * // init — grants cloudwatch:GetMetricData
 * const getMetricData = yield* AWS.CloudWatch.GetMetricData();
 *
 * // runtime
 * const now = yield* Effect.sync(() => Date.now());
 * const result = yield* getMetricData({
 *   StartTime: new Date(now - 3_600_000),
 *   EndTime: new Date(now),
 *   MetricDataQueries: [
 *     {
 *       Id: "m1",
 *       MetricStat: {
 *         Metric: { Namespace: "MyApp/Payments", MetricName: "PaymentProcessed" },
 *         Period: 60,
 *         Stat: "Sum",
 *       },
 *     },
 *   ],
 * });
 * const series = result.MetricDataResults ?? [];
 * ```
