Rewrite vps/firstboot-vps.sh as phase-1 only: partition disk,
create ZFS pool "clawdie", install FreeBSD base, inject firstboot
payload, install bootloader, reboot. On first HDD boot the standard
firstboot.sh modular pipeline runs (zfs detect, wizard, gpu, pkg,
ssh, env, system, tailscale, deploy).
Pre-baked clawdie.conf values get written to build.cfg with
TARGET=cloud so the wizard is skipped. Pool named "clawdie"
(not zroot) for pool detection compatibility.
Remove duplicate clawdie-vps-setup.sh.
