In general I believe it's clever to synthesize an index for single-platform image manifest, but we still need a way to distinguish it. Add a dedicated annotation is the slightest change I've come up with, and it's also OCI compliant. With this change come in, we can work around https://github.com/apple/container/issues/212 and imitate the behavior of other runtime with `container`. Note that since `cctl` is meant to be a dedicated tool for inspecting the Containerization framework itself, I didn't apply the indirection for it, and it will be as-is with the genuine storage.
