If /sys/class/dmi/id/sys_vendor says DigitalOcean and the droplet has a reserved_ip or floating_ip assigned, use that over the ipify-based egress IP. Keeps the ipify/hostname -I fallback intact for other hosts. Gated on the DMI check so non-DO hosts skip the metadata probe entirely and the tmux status bar refresh stays fast.
