"""通用步骤任务定义。

前端步骤编辑器编排步骤链，保存为 params.steps（JSON 数组）。
|

worker 按 steps 顺序执行，支持 loop 步骤循环、停止信号、进度上报。

步骤 schema:

"label": "打开抖音", # 用户可读名称

"params": { ... } # 步骤参数（按 type 不同）

支持的步骤类型：
|
||
open_app - 启动 app
|
||
swipe - 滑动（方向/时长）
|
||
click - 点击元素（选择器）
|
||
input_text - 输入文字（随机候选/指定文字）
|
||
wait - 等待时长
|
||
loop - 循环块（含 children 步骤列表 + max_iterations）
|
||
group - 动作组（含 children 步骤列表，按序执行一次，可折叠复用）
