Story Crater BotandClaude Haiku 4.5 e7f3409d0f feat(phase0): bootstrap External Secrets Operator and fix helmfile dual-ownership
Phase 0 groundwork for helmfile→ArgoCD migration:

1. Remove 3 bootstrap releases from helmfile (cert-manager, reloader, ingress-nginx)
   — already managed by terraform/bootstrap-releases.tf; eliminates dual-ownership

2. Bootstrap ESO (External Secrets Operator) as TF-managed release
   — required for all ExternalSecret resources in phases 1-3
   — added to bootstrap-releases.tf + helm-repositories.tf

3. Create ClusterSecretStore connecting ESO to Vault (K8s auth)
   — enables per-namespace/per-release secret injection
   — vault config documented in docs/PHASE0-ESO-VAULT-SETUP.md (manual setup)

4. Fix argocd-bootstrap.tf CA cert copy: use jq instead of sed for cleaner metadata handling

Changes:
- helmfile.yaml.gotmpl: remove cert-manager/reloader/ingress-nginx blocks
- terraform/bootstrap-releases.tf: add external-secrets release
- terraform/helm-repositories.tf: add external-secrets Helm repo
- k8s/external-secrets/clustersecretstore.yaml: ESO→Vault ClusterSecretStore
- k8s/argocd/apps/0-wave-0.yaml: stub wave 0 applications (schema fix, rewrite pending Phase 1)
- docs/PHASE0-ESO-VAULT-SETUP.md: manual ESO-Vault auth setup procedure

Next: Phase 1 will incrementally rewrite ArgoCD Applications + migrate helmfile releases.

# MinIO - Official minio/minio chart, direct Helm deployment (no operator)
# All-in-one: single helm_release + dedicated xfs StorageClass.
# Why xfs: default `longhorn` SC uses ext4 whose mkfs on 100Gi (~4.5min)
# exceeds kubelet mount timeout. xfs mkfs is near-instant. min.io chart has
# no persistence.fsType, so fsType must be set on the StorageClass.
#
# PVC is Terraform-managed directly (import-only, prevent_destroy) and
# referenced by the chart via persistence.existingClaim, so Helm never
# templates/reconciles the PVC object itself (previously caused a failed
# force-replace attempt against the bound, immutable volumeName).
