Add optional interfaces that providers can implement beyond the base Manager. grlx can type-assert to check support at runtime: - VersionQuerier: LatestVersion, ListUpgrades, UpgradeAvailable, VersionCmp - Holder: Hold, Unhold, ListHeld (version pinning) - Cleaner: Autoremove, Clean (orphan/cache cleanup) - FileOwner: FileList, Owner (file-to-package mapping) - RepoManager: ListRepos, AddRepo, RemoveRepo - KeyManager: AddKey, RemoveKey, ListKeys (GPG signing keys) - Grouper: GroupList, GroupInfo, GroupInstall - NameNormalizer: NormalizeName, ParseArch Also adds GetCapabilities() helper, Repository type, and updated README.
