+/**
+ * Gate REST API 执行器。
+ *
+ * <h3>设计目的</h3>
+ * WebSocket 消息在回调线程中处理（如 {@code WebSocketClient} 的 {@code onMessage} 线程）。
+ * 下单 REST API 调用可能耗时数百毫秒，若同步执行会阻塞 WS 回调线程，导致心跳超时误判。
+ * 本类将所有 REST 调用提交到独立线程池异步执行。
+ *
+ * <h3>回调设计</h3>
+ * 每个下单方法接受 onSuccess/onFailure 两个 Runnable。
+ * 基底开仓时 onSuccess 用于标记基底已开，网格触发时通常为 null（成交状态由仓位推送驱动）。
+ *
+ * <h3>线程模型</h3>
+ * <ul>
+ * <li><b>单线程</b>：保证下单顺序（开多→开空→止盈单），避免并发竞争</li>
+ * <li><b>有界队列 64</b>：防止堆积。极端行情下最多累积 64 个任务</li>
+ * <li><b>CallerRunsPolicy</b>：队列满时由提交线程直接同步执行，形成自然背压</li>
+ * <li><b>allowCoreThreadTimeOut</b>：60s 空闲后线程回收，不浪费资源</li>
+ * </ul>
+ *
+ * <h3>调用链</h3>
+ * <pre>
+ * GateGridTradeService.onKline → executor.openLong/openShort (基底双开 + 网格触发)
+ * GateGridTradeService.onPositionUpdate → executor.placeTakeProfit (开仓成交后设止盈)
+ * GateGridTradeService.stopGrid → executor.cancelAllPriceTriggeredOrders
+ * </pre>
