## Summary This commit changes the USER instruction in our Dockerfiles from using the string "nonroot" to its numeric ID "65532". This change is necessary because Kubernetes does not support string-based user IDs in security contexts, requiring numeric IDs instead. The nonroot user maps to 65532 in distroless images.
