Reverting Phase 4 Pod Job implementation in favor of CI runner (Forgejo Actions). Deleted: - k8s/argocd/apps/phase4-terraform-0.yaml - k8s/hooks/phase4/ (terraform-apply-hook.yaml, terraform-rbac.yaml, terraform-s3-secrets.enc.yaml) Reason: Pod Job approach had limitations (eviction, timeouts, pod security policies). Next: Implement Forgejo Actions CI workflow for terraform apply.
