ek-ui 0.2.18

//! `UiPlugin` —— 总线面:`eLog` 入环形日志、`ePlugUp/Down` 记事件 + rev、
//! `eBar`./`eBarUpdate.` 记行情库(K线窗数据面)、`eTick.` 记 tick 库(v4 行情带
//! 唯一源,S7 上屏地面)、
//! `eTimer`(1s 宿主自带)拉一次 `svctl.list` + 逐插件服务目录组快照 +
//! ask oms 全量查询组交易监控帧(S5),
//! 并辞行窗口面的操作指令队列(svctl 起停 + dm.reload 回灌 + oms 五段管线
//! 下单/守卫撤单)。
//!
//! 纪律:UI 不直调任何插件;唯一管制面是 ask 契约(svctl / dm.reload /
//! oms 查询与 submit_order·cancel_order / ctp 配置订阅,全部与
//! headless 同源;`PluginContext` 只在 worker 可用)。0.1.1 BD-UI-30:
//! 下单/撤单直发网关的旁路口删除——风控与守卫不可绕过。0.2.10 BD-UI-38:
//! sim 纸面网关退场(流控查询口随之撤)。
