Delete old terraform-apply.yml (terraform fmt/init/validate/plan/apply). Create new GitOps CI/CD: - validate-k8s.yaml: YAML lint, kubeval, kustomize build, ArgoCD validation - argocd-sync.yaml: Auto-sync homelab-root on main branch - security-scan.yaml: Trivy, Polaris, secret detection - .yamllint.yaml: YAML linting configuration Add documentation (.forgejo/CI-CD.md) and architecture guides. Git is now single source of truth. CI validates, ArgoCD deploys.
