/**
- * Gate K线 WebSocket 客户端类，用于连接 Gate 的 WebSocket 接口，
- * 实时获取并处理 K线（candlestick）数据。
- * 同时支持心跳检测、自动重连以及异常恢复机制。
+ * Gate WebSocket 连接管理器。
+ *
+ * <h3>职责</h3>
+ * 负责 TCP 连接的建立、维持和恢复。频道逻辑（订阅/解析）全部委托给 {@link GateChannelHandler} 实现类。
+ *
+ * <h3>生命周期</h3>
+ * <pre>
+ * init() → connect() → startHeartbeat()
+ * destroy() → unsubscribe 所有 handler → closeBlocking() → shutdown 线程池
+ * onClose() → reconnectWithBackoff() (最多 3 次，指数退避)
+ * </pre>
+ *
+ * <h3>消息路由</h3>
+ * <pre>
+ * onMessage → handleMessage:
+ * 1. futures.pong → cancelPongTimeout
+ * 2. subscribe/unsubscribe → 日志
+ * 3. error → 错误日志
+ * 4. update/all → 遍历 channelHandlers → handler.handleMessage(response)
+ * </pre>
+ *
+ * <h3>心跳机制</h3>
+ * 采用双重检测：TCP 层的 WebSocket ping/pong + 应用层 futures.ping/futures.pong。
+ * 10 秒未收到任何消息 → 发送 futures.ping；25 秒周期检查。
+ *
+ * <h3>线程安全</h3>
+ * 连接状态用 AtomicBoolean（isConnected, isConnecting, isInitialized）。
+ * 消息时间戳用 AtomicReference。心跳任务用 synchronized 保护。
+ *
