refactor(ci-cd): Replace Terraform pipeline with GitOps validation and ArgoCD sync
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.
