in general this is lgtm in approach for the artifact downloader, but:
- I was expecting the download resource to be fixed alongside, i only see ocm download artifact. whats the behavior for downloading resources with a downloader
- I think the test is not setup stable. you expect the docker daemon to be available but we should test against an actual OCI registry imho. nothing that will block the PR though

Im pretty sure that this is breaking backwards compatibility. That is because the oci layout flag was present before and I believe we can now no longer read from layouts that had the "old" incorrect oci layout flag. I think we need to version this off... I have encountered a very similar issue during my testing of local blob compatibility

<!-- markdownlint-disable MD041 --> This change adds an optional --oci-layout flag to the `ocm download artifacts|resources` command to store blobs at blobs/<algorithm>/<encoded> per OCI Image Layout Specification instead of the default blobs/<algorithm>.<encoded> format. This enables compatibility with tools that expect OCI-compliant blob paths. <!-- Usage: `Fixes #<issue number>`, or `Fixes (paste link of issue)`. --> Fixes open-component-model#1668 Signed-off-by: Piotr Janik <[email protected]>
