/**
 * @file WaveHudComp.ts
 * @description 波次进度 HUD 组件（表现层）
 *
 * 职责：
 *   1. 本回合清剿进度：剩余怪数（mon_num + pending_mon_num）+ 进度条。
 *   2. 全局 20 回合进度格：静态生成，Boss 回合（wave%5==0）置旗帜样式，当前回合脉动、已过回合置灰。
 *
 * 数据流：NewWave 事件缓存 total/wave；update 0.2s 降频轮询 vmdata（与 syncMonsterSpawnState 同节奏）。
 * 使用 oops-framework 模块：oops.message（事件解耦）。
 *
 * 编辑器绑定：waveLab / remainLab / progress / flagsRoot（水平 Layout 容器，20 格代码生成）。
