## Summary
- Upgrade External Secrets Operator from v1.3.2 (helm-chart-2.0.0) to v2.2.0
- Migrate from Helm chart deployment to static kustomize manifests, matching the repo's kustomize-first pattern
- Merge separate `-config` ArgoCD apps into the main operator apps (6 → 4 apps)
- Clean up Helm-specific labels (`helm.sh/chart`, `managed-by: Helm`)
- Update README example from v1beta1 to v1 API
## Breaking changes assessment
Low risk — v2.0.0 removed Alibaba and Device42 providers (we use neither). No templating changes affect us. All ExternalSecrets already use v1 API.
## Deployment steps
1. Sync CRDs first on both clusters (new CRD version)
2. Sync operator apps (now kustomize-based)
3. Verify ClusterSecretStore and all ExternalSecrets are healthy
4. Delete orphaned config apps: `argocd app delete external-secrets-config` and `-config-ringtail`
5. `mise run services-check`
