feat: add named Cloudflare tunnel support

Browse Source 
Add named tunnel mode alongside existing quick tunnel, with systemd
service and setup helper. All tunnel parameters are configurable via
environment variables:

  CLOUDFLARED_TUNNEL_NAME   — tunnel name (default: codeman)
  CLOUDFLARED_TUNNEL_ID     — tunnel UUID (from: cloudflared tunnel list)
  CODEMAN_TUNNEL_HOSTNAME   — public hostname

Backward compatible: ./tunnel.sh [start|stop|status|url] still works.
