reCAPTCHA v2 图像识别

把 reCAPTCHA 弹出的九宫格图片交给平台判断，自己控制点击流程。

适合你已经能驱动浏览器、只想让平台帮忙「看图」的场景。每次传一张小图块 + 一个问题 ID，返回该图是否属于这个问题。你需要自己循环：点图 → 重新截图 → 再问。

注意事项

• 常用 question：/m/0k4j 汽车、/m/01g317 公交车、/m/015qff 消防栓、/m/01bjv 自行车、/m/0pg52 出租车、/m/02y_9m3 红绿灯、/m/04bcr3 人行横道。
• 实际业务里 question 从页面的 data-sitekey 附近或接口响应里抓。
