/**
 * Gate 模块入口管理类，作为 Spring Bean 负责组件的生命周期。
 *
 * <h3>启动流程</h3>
 * <pre>
 *   @PostConstruct init():
 *     1. new GateGridTradeService(参数) → init()     // 设杠杆、查余额、切双向持仓
 *     2. new GateKlineWebSocketClient → init()        // 连接 WebSocket，订阅 K 线 + 仓位
 *     3. gridTradeService.startGrid()                 // 激活策略，等待 K 线触发首次双开
 * </pre>
 *
 * <h3>销毁流程</h3>
 * <pre>
 *   @PreDestroy destroy():
 *     1. gridTradeService.stopGrid()                  // 停止策略
 *     2. klinePriceClient.destroy()                   // 取消订阅 → 关闭 WS → 关闭线程池
 * </pre>
 *
 * <h3>配置参数</h3>
 * 当前配置在代码中硬编码：
 * <ul>
 *   <li>合约: XAU_USDT, 杠杆: 30x, 全仓, 双向持仓</li>
 *   <li>网格间距: 0.35%, 整体止盈: 0.5 USDT, 最大亏损: 7.5 USDT</li>
 *   <li>数量: 10 张</li>
 * </ul>
