fix: 元素抓取生成精确选择器,无属性元素用锚点祖先限定;抖音点赞找不到按钮不再双击屏幕

- 元素选择器生成:无 resource-id/text 的元素改用最近有唯一属性祖先限定范围,
  并带同 class 兄弟序号消歧(如 //*[@resource-id=".."]/RelativeLayout[3]),
  不再给裸 class(如 //android.widget.ImageView 会误匹配其他元素)
- 仍无法限定的宽泛选择器标记 broad,前端元素列表显示"⚠宽泛"提示
- 抖音 like 动作:by_element 找不到点赞按钮改为跳过,不再双击屏幕中央(避免误触)

两种方式:
by_element — 用 xpath 找右侧红心按钮点击(相对定位,不依赖视频卡片序号)
double_click — 双击屏幕中央(兜底,不依赖元素,抖音"双击点赞"手势)

定位器随抖音版本变,by_element 找不到会自动回退双击,不会卡住。
by_element 找不到点赞按钮时**跳过本次,不点屏幕**(避免直播/无按钮页误触)。
要适配新版本抖音:用 weditor 重新抓当前界面,调整下面定位逻辑。
