# mode_procedure 查看服务 + Cloudflare 隧道 一键管理脚本
#
#   ./share.sh start     启动 server.py(后台) + cloudflared 隧道(后台,http2)，打印公网链接
#   ./share.sh stop      停掉两者
#   ./share.sh restart   重启两者(换新链接)
#   ./share.sh status     查看运行状态 + 当前链接
#   ./share.sh url        只打印当前公网链接
#
# 设计要点:
#   - 两个进程都用 nohup/setsid 脱离终端，关掉终端窗口也不会被 SIGHUP 杀掉。
#   - cloudflared 强制 --protocol http2，绕开公司网/VPN 常封的 UDP(QUIC)。
#   - 幂等:重复 start 会先清掉旧进程，不会起一堆。
