Add docker.io mirror configuration to the generated buildkitd.toml so BuildKit tries the local registry first when pulling base images (e.g., FROM node:20-alpine). Falls back to Docker Hub if not found locally. This avoids redundant Docker Hub pulls when base images have already been mirrored to the local registry, without needing Dockerfile rewriting or other application-level workarounds.

Summary
[registry."docker.io"] mirrors = ["{local-registry}"]to the generatedbuildkitd.tomlin the builder agentFROM node:20-alpine(or any docker.io image), it tries the local registry first, falling back to Docker Hub if not foundPrerequisites for production testing
Base images need to be available in the local registry for the mirror to provide a hit. This can be done by pulling them into hypeman's registry ahead of time (e.g., via the images API).
