/**
- * Gate WebSocket 客户端，通过 Java-WebSocket 库连接 Gate.io 的 WebSocket 接口。
+ * Gate WebSocket 连接管理器。
+ * 负责建立连接、心跳检测、重连，将频道逻辑委托给 {@link GateChannelHandler} 实现类。
*
- * <h3>订阅频道</h3>
- * <ul>
- * <li>{@code futures.candlesticks} — 1m K 线数据（公开频道）</li>
- * <li>{@code futures.positions} — 用户仓位更新（私有频道，需 HMAC-SHA512 签名认证）</li>
- * <li>{@code futures.ping} — 应用层心跳</li>
- * </ul>
- *
- * <h3>数据流</h3>
- * <pre>
- * onMessage → handleWebSocketMessage → 按 channel 分流:
- * futures.pong → 取消心跳超时
- * subscribe/unsubscribe/error → 日志
- * futures.candlesticks → processPushDataV2 → GateGridTradeService.onKline()
- * futures.positions → processPositionData → GateGridTradeService.onPositionUpdate()
- * </pre>
- *
- * <h3>连接管理</h3>
- * 支持心跳检测、指数退避重连（最多 3 次）、优雅关闭。
+ * <h3>频道处理</h3>
+ * 每个频道由独立的 Handler 类负责：订阅、取消订阅、消息解析。
+ * 运行时将消息按 channel 字段路由到对应 Handler。
