Remove the monolithic utils::fetch module (HTTP download, git clone, checksum, extraction) and utils::fetch_plugin module from the baker. Introduce a ResourceRegistry type to centrally track pipeline resources by name and path. The actual fetching logic is now delegated to the workshop-getterurl crate, which gains optional md5 and sha1 hash support behind default features. Also flatten the builtin module in workshop-getterurl.
