feat: 增强版验证码全套实现 — 16种类型生成器/加密/风控/站点管理/平台后端/前端SDK/UI
- 核心新增: ICON_CLICK(PNG图标方案,预渲染资源)/SCRATCH/JIGSAW/CURVE_SLIDER(V1-V3)/ANGLE/CURVE_DRAW/WORD_ORDER_CLICK/PROOF_OF_WORK 等生成器 - 图标点选: classpath PNG 加载替代运行时字体渲染(Linux容器无emoji字体),提示条图作为 templateImage 返回前端 - 新增模块: crypto(AES+RSA)/obfuscator(背景乱序/噪声/扭曲)/risk(风控/IP黑名单/限流)/site(站点管理)/ml(轨迹规则引擎) - 平台后端: 站点管理/验证码API(generate/verify/secondary-verify)/统计/ML轨迹学习 - 前端SDK: TPCaptcha兼容,支持全部新型号渲染与交互 - 工具: tools/icon-render 图标预渲染工具
