"""
QQ 主动发文件脚本 - 后台发送

原理：
  1. 立即返回（fire-and-forget），不阻塞 agent
  2. 后台独立进程：复制 → 删除旧文件 → 通过 NapCat API 发文件
  3. 文件发送即完成，不再额外通知 agent

用法:
  python3 qq_send_file.py --private YOUR_ADMIN_QQ /path/to/file
  python3 qq_send_file.py --group YOUR_GROUP_ID --name "报告.txt" /tmp/report.txt
  python3 qq_send_file.py --group YOUR_GROUP_ID --image /tmp/screenshot.png
