feat(downloader): wire ArchiveDownloader extraction and Path/Zip overrides

Implement ArchiveDownloader for Zip/Tar/Gzip/Xz/Phar/Rar so install()
extracts the archive (extract + rename) instead of doing FileDownloader's
plain file rename, and route install/prepare/cleanup through the mixin.
ArchiveDownloader::extract becomes &mut self to match the concrete
implementations.

Route ZipDownloader's bespoke download() (unzip-command static init) and
PathDownloader's symlink/junction/mirror download/install/remove through
the DownloaderInterface trait (path: String -> &str).
