fix: disable aws-ebs-csi-driver by default on EKS

[yuanchen8911]

Summary

• Disable aws-ebs-csi-driver subchart by default in the EKS overlay

Problem

EKS clusters typically have the EBS CSI driver installed as a managed addon. When eidos deploys it again, Helm fails with:

Error: INSTALLATION FAILED: unable to continue with install: ClusterRole "ebs-external-attacher-role"
exists and cannot be imported into the current release: invalid ownership metadata;
label validation error: key "app.kubernetes.io/managed-by" must equal "Helm": current value is "EKS"

Confirmed EBS CSI controller pods already running in kube-system as EKS-managed addon.

Changes

• Modified: pkg/recipe/data/overlays/eks.yaml — added overrides: enabled: false to aws-ebs-csi-driver component

Users without the managed addon can re-enable with: --set aws-ebs-csi-driver.enabled=true

Test plan

• go test ./pkg/recipe/... ./pkg/bundler/... — all pass
• Generated bundle shows aws-ebs-csi-driver.enabled: false
• helm install no longer fails with ClusterRole conflict on EKS
