/**
|
* K 线（Candlestick）频道处理器。
|
*
|
* <h3>特点</h3>
|
* 公开频道，无需 HMAC-SHA512 认证签名。订阅 1m 周期的 K 线数据。
|
*
|
* <h3>数据流</h3>
|
* <pre>
|
* WebSocket 推送 update event
|
* → handleMessage() → 解析 OHLCV → log 打印 → gridTradeService.onKline(closePx)
|
* → WAITING_KLINE: 首次 K 线触发基底双开
|
* → ACTIVE: 驱动 processShortGrid + processLongGrid 网格触发
|
* </pre>
|
*
|
* <h3>订阅格式</h3>
|
* payload: {@code ["1m", contract]}
