feat(video-analysis): 抖音免浏览器解析链路 + 快手支持 + 小红书加固 + 发送防重复

- 抖音（2026-10-13）：删除 SSR + playwright 旧链路（douyin_ssr.py 移除，
  douyin_api.py 精简为下载工具），新增 douyin_web.py（x-tt-argus 网关头 +
  web detail 接口 + 最高码率梯/多 CDN 回退下载）与 douyin_sign.py
  （纯 Python a_bogus 签名，vendor 自 f2（Apache-2.0），依赖 gmssl SM3）；
  实测 10/10 成功率、单作品 <1s（旧浏览器链路 5-15s 且随机撞验证码）
- 快手（2026-10-08）：kuaishou_content.py 分享页 INIT_STATE 静态解析（无登录态），
  清晰度梯最佳档 + 图集 URL 组装，入口/策略/Web 面板同步接入
- 小红书：按链接来源定国际/国内站优先序、视频 backupUrls 逐候选回退、
  图片 urlDefault→infoList WB_DFT→url 三档回退
- 长视频防重复发送（2026-10-13）：媒体发送带 per-call _timeout（默认 300s），
  超时=结果未知不再降级重试；auto/active 两条 handler 互斥
- Web 解析封面抽帧 ffmpeg 加 CREATE_NO_WINDOW（pythonw 下不再弹 cmd 黑窗）
- 依赖：+gmssl；测试：新增 test_douyin_web / test_kuaishou_parse / test_video_cleanup，
  扩充 test_video_policy / test_video_sender_link / test_video_group_file / test_video_media_naming
