Interactive onboarding runbook for standing up FoliaNexa's public-facing infrastructure — a VPS edge (WireGuard tunnel, Caddy TLS, portal), its DNS records, and trusting one or more LXD hosts (e.g. 3 machines) into the cluster. Use when the operator says things like "help me set up my VPS", "configure DNS", "onboard my LXD servers", "bootstrap the cluster infra", or wants to walk through CLAUDE.md's Phase 0/3/9 or docs/vps-edge-deployment.md interactively instead of reading the docs cold. Drives real commands on whichever machine the session is running on (VPS, an LXD host, or a jump box with SSH to both), tracks progress across machines/sessions in a small local checklist file, and never invents infrastructure details (domains, IPs, tokens) — always asks.
