This reverses how the airgapped container images were working. During preparation, the `index.json` is now trimmed down to be loadable by podman and docker. The original `index.json` is kept in the archive as `dangerzone.json`. This has two benefits: 1. The image is now loadable by a container engine without changes; 2. There is no more a need to recreate the archive at runtime, leading to less CPU and space usage on the user device.
