Implement a lightweight cloud-init system for first-boot configuration: - Go parser for YAML config (hostname, network, KubeSolo settings) - Static/DHCP network modes with DNS override - KubeSolo extra flags and API server SAN configuration - Portainer Edge Agent and air-gapped deployment support - New init stage 45-cloud-init.sh runs before network/hostname stages - Stages 50/60 skip gracefully when cloud-init has already applied - Build script compiles static Linux/amd64 binary (~2.7 MB) - 17 unit tests covering parsing, validation, and example files - Full documentation at docs/cloud-init.md Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

// - NTP servers
