/**
 * 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 客户端，通过 Java-WebSocket 库连接 Gate.io 的 WebSocket 接口。
 *
 * <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。
