Add the zip format of a package (a digest manifest plus the files of the OCI package for one platform) and an addonpkg zip subcommand that writes it from a verified layout, with a sha256 file. The zip comes from the same layout the registry package comes from, so there is one build path. Version comparison moves to contract.CompareVersions so the installer can use it for upgrades and downgrades. Assisted-by: Claude:claude-sonnet-5-5 go gofmt
