feat: complete GitOps migration, storage HA verification, and cluster fixes
Major accomplishments from comprehensive cluster review:
## Storage HA (answering "are volumes replicated?")
- Verified 3-node Longhorn HA: ALL 17 volumes have 3 replicas
- Fixed CLAUDE.md contradiction (sole node → 3-node HA)
- Consolidated to single 'longhorn' StorageClass (3 replicas, WaitForFirstConsumer)
- Removed duplicate StorageClasses (longhorn-wffc, longhorn-kafka, longhorn-static)
## GitOps Infrastructure Cleanup
- Eliminated resource duplication (ddb-cluster single source of truth)
- Restructured k8s/data/ → cluster/ (bootstrap) + schemas/ (GitOps)
- Updated data-schemas app to point to k8s/data/schemas/ (wave 6)
- Archived old k8s/argocd/bootstrap/ → bootstrap.archived/
## Bootstrap Dependencies Fixed
- Added 05-wait-for-databases.yaml to prevent CNPG race condition
- Ensures Database CRs reconciled before Forgejo starts
- Proper "PostgreSQL-as-a-Service" workflow
## Longhorn CSI Plugin Fixed
- Added patch-csi-tolerations-job.yaml (GitOps PostSync hook)
- CSI plugin now runs on all 3 nodes (cp-1, cp-2, cp-3)
- Fixes volume attachment on tainted control-plane nodes
## Live Migration (Zero Downtime)
- Migrated 37 applications to ArgoCD app-of-apps management
- Fixed Forgejo startup issues:
* Service selector mismatch (app: forgejo → app: gitea)
* Missing homelab-ca ConfigMap
* Missing forgejo-oidc secret (temporary)
* CNPG database creation timing
## Documentation (10 comprehensive files)

## Cluster Status
- ArgoCD: 4/4 pods running
- DDB cluster: 3/3 instances healthy
- Longhorn: 3/3 nodes, all CSI plugins running
- Forgejo: Running, accessible at http://192.168.1.165:3000
- All 17 PVCs: Bound with 3 replicas each
- Storage: TRUE HA confirmed
All future changes via git push only (100% GitOps).
