feat(twitter): t.co 替换 + yt-dlp 进度心跳 + access_key 全脱敏

P3 #16 t.co 处理(关键):主站审核 LLM 看到 t.co 短链会判成"联系方式/广告"导致
  Twitter 推文大量被拒(NASA 15 条只入 11 条因为这个)。改:
    - 媒体 t.co(entities.media[].url):直接删
    - 外链 t.co(entities.urls[].url):替换成 expanded_url(真实目的地址),
      LLM 看到 nasa.gov/blog/xxx 就不再误判
    - 正则兜底删任何残留的 https://t.co/xxx
  原始 full_text 存进 extra_data.original_full_text 备查。
P3 #14 yt-dlp 进度心跳:download_video 加 on_progress 回调,jobs.py 传 _log 进去。
  yt-dlp 的 progress_hooks 每跨 10% 或 5 秒打一行(节流),exec_log 里能看到
  「↓ 35% 12.3MB/35.0MB @ 1024KB/s」,大视频不再发冷。
P3 #15 MinIO access_key 全脱敏(从前4位+*** → 全 ***)。
