feat(反VM): 纯 Python 还原 XTEA 算法 + 从 tdc.js 运行时提取每构建密钥

Browse Source 
做了什么
- 确认 collect 的加密算法就是教科书 XTEA (32 轮, delta=0x9E3779B9),
  并证明 crypto.py 原有的"带加盐"写法只是把两个密钥字折叠:
  K' = [k0, k1+salt1, k2+salt2, k3]
- tdc_worker.js 新增 captureKey 模式: 正则改写 VM 的 ADD/XOR opcode 为带日志版本,
  用反向引用自动识别栈变量名 (样本=g/雨云实时=j/1ms=M, 版本无关);
  匹配数不为 1 时显式报错, 不静默失败
- 密钥反推: (sum + K[j]) 是一次 ADD, 两操作数必有一个等于 r*DELTA,
  另一个就是密钥字; 再对 Top-N 候选做 4! 排列 + 明文内容特征验证
- 新增 recover_payload_template / generate_collect_from_template:
  运行时标定一次明文模板, 之后轨迹生成/组包/加密/编码全部在 Python
- 新增 tcaptcha/proxy.py 代理提取, client 支持 --proxy-api 遇 12 自动换 IP

为什么
- 服务端只认 collect 的解密结果, 而密钥是每构建随机的;
  把算法做成纯 Python 后, 只有"取密钥"依赖 Node, 抗发版能力最强

怎么验证的
- 纯 Python XTEA 加密结果与真实 tdc.js 产物前 48 字节逐字节一致
- 密钥按构建固定的证据: 同一脚本 3 次运行密文首块均为 f6a24e3e4fb5dd2b
- 三份脚本 (样本/雨云实时/1ms实时) 均成功复原密钥
- 雨云 aid 端到端: 纯 Python 出包 -> errorCode=0 + 真实 ticket
- 回归测试: tcaptcha/tests/test_xtea_key.py 11 项断言全过,
  文字点选求解 8/8; 新增 tcaptcha/selftest.py 一键复验

已知未解
- 1ms aid=195672344 在答案正确时仍返回 errorCode=12; 已排除密钥、
  遥测引擎、出口 IP (4 个住宅代理)、短时频控、静默窗口

腾讯天御点选验证码工业级纯协议客户端 (Tencent Turing Captcha Protocol Client)
实现端到端全自动纯协议闭环：
1. GET /cap_union_prehandle 获取初始会话与 PoW 题目
2. 毫秒级求解 Proof of Work 哈希碰撞
3. 并发拉取动态混淆的 tdc.js 脚本
4. POST /cap_union_new_getsig 获取当前轮次题目与图片
5. YOLOv8n + ResNet18 模型进行视觉检测、分类与全局非冲突点选排序
6. 纯算法还原 (Custom XTEA + 贝塞尔人手微颤) 生成行为轨迹密文 collect 与会话密钥 eks (100% 纯 Python)
7. POST /cap_union_new_verify 提交验证，获取最终 ticket 与 randstr
腾讯天御点选验证码纯协议客户端 (Tencent Turing Captcha Protocol Client)
覆盖腾讯天御 `cap_union_new` 协议族的完整纯协议闭环:
1. GET /cap_union_prehandle 获取会话 sess / PoW 题目 / 题型 / 首道题目
2. 本地求解 PoW (MD5 哈希碰撞)
3. GET <tdc_path> 拉取当前会话动态混淆的 tdc.js, 提取会话密钥 eks
4. GET /cap_union_new_getcapbysig 下载 672x480 背景图 (img_index=1);
图标题型额外下载 img_index=0 提示图
5. 视觉求解:
* 文字点选 (subcapclass 2404) -> tcaptcha.glyph_solver.TextClickSolver
* 图标点选 (subcapclass 2408) -> tcaptcha.solver.CaptchaSolver (YOLO+ResNet18)
6. 生成行为遥测密文 collect (纯 Python 还原的自定义 XTEA + 贝塞尔轨迹)
7. POST /cap_union_new_verify 提交 ans/collect/eks/sess/pow_answer
8. 失败 → POST /cap_union_new_getsig 在同一会话内刷新下一道题并重试
题型识别不依赖 subcapclass 数字 (getsig 不返回该字段), 而是根据
instruction + bg_elem_cfg.click_cfg 推断, 详见 classify_challenge()。
