feat(captcha): 增加全题型图片落盘、字形一致性强校验与防秒换拟人交互机制
- 题目图片自动下载: 所有题型原图统一落盘至 scratch/captcha_debug，文字点选自动生成带编号红圈标注图便于肉眼核验 - 字形严格一致性校验: 在 SolveResult 增加 text_match_ok 检查，对图字不符或混淆干扰题直接拒答换题，避免错答引发 errorCode=12 - 防秒换与拟人延时: 遇到非预期题目换题等待 2.8~4.2s (对齐 HAR 真实抓包)，求解失败等待 2.5~3.8s，作答前模拟交互 5.5~7.5s - 代理容错增强: 在 OneMsAdapter 捕获代理断流与鉴权异常，支持动态轮换新代理重试
