Go service for Proxmox homelab cluster provisioning. Handles PXE boot, Proxmox autoinstall (answer file generation), cluster join via SSH, and Infrastructure API registration. - Host state machine (registered → pxe_ready → installing → ready) - dnsmasq supervisor with MAC-based allowlist - iPXE script and Proxmox answer file generation - First-boot phone-home → cluster join → infra registration - Operation locking with expiry (409 on conflict) - SSE event hub for real-time dashboard updates - Admin dashboard (host grid, detail, registration form) - Config-driven server types with hot-reload - Docker deployment (multi-stage fat image) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
