Month 1-OCI Foundations: Specs, runc, skopeo, crun¶

Goal: by the end of week 4 you can (a) hand-author an OCI runtime config.json and run a container with runc directly, (b) push, pull, and copy images between registries with skopeo without ever touching a daemon, (c) read an image manifest, layer hashes, and config blob, and (d) explain the difference between runc and crun and pick one for a workload.
