* @brief 喷淋作业引擎：一轮 = 单次时长 × 次数 + 间隔（规格书第 10 章）
|
||
* @author cyWu <1917507415@qq.com>
|
||
* @date 2026.09.09
|
||
* @version V1.0.0
|
||
* @history
|
||
* - V1.0.0, 2026.09.09, cyWu, P0 首次发布（默认 10s×3 次+3s，只跑一轮）
|
||
*
|
||
* @note 本模块是**唯一切泵者**（规格书 7.2）：键/DP/联动/计划都只请求
|
||
* "开一轮 / 停"。20ms 节拍倒数，禁止阻塞 delay。间隔等待也算作业态
|
||
* （DP1=1、绿灯继续闪），但泵已关、不记运行秒（P2 由 app_runrec 负责）。
