New hetzner/ directory with step-by-step Proxmox setup guide (networking,
WireGuard, firewall, storage, API tokens) and an interactive helper script
that automates all steps over SSH.
New incusos/targets/ layout with per-host connection configs and lab
definitions for beelink and hetzner targets. No changes to incusos-proxmox
itself -- uses existing --proxmox flag.
