Subject: [PATCH] feat(phase0): setup SOPS for encrypted secret management
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 0 groundwork for helmfile→ArgoCD migration using SOPS (Secrets Operations):

1. Install SOPS + AGE encryption
   - AGE key generated and stored locally at ~/.sops/key.txt
   - Public key embedded in .sops.yaml for file encryption rules

2. Create K8s Secret for AGE private key
   - kubectl: create secret generic sops-age -n argocd --from-file=keys.txt=~/.sops/key.txt
   - ArgoCD will use this key to decrypt secrets at sync time

3. Encrypt initial secrets
   - k8s/base/secrets.enc.yaml: AES256_GCM encrypted secrets for all services
   - Placeholder values (will be replaced with real values per environment)
   - Secrets never visible in git (encrypted at rest)

4. Configure SOPS
   - .sops.yaml: creation rules for k8s/*/secrets.enc.yaml files
   - All future secret files auto-encrypt on edit (sops -e)

Setup: Store AGE key as K8s Secret in argocd namespace:
  export KUBECONFIG=cluster-config/kubeconfig
  kubectl create secret generic sops-age -n argocd --from-file=keys.txt=~/.sops/key.txt

Next: Configure ArgoCD Helm plugin to decrypt secrets on sync (Phase 0 continuation).
