Add zstd and tar as Rust dependencies and rewrite the artifact installation logic to extract only the component tarballs required by the enabled runtime classes. extract_component_tarballs reads shim-components.json to determine which kata-static-<name>.tar.zst files are needed for the selected shims and current architecture. Shared components (e.g. kernel, shim-v2-go) are listed by multiple shims and must only be unpacked once per install run. Deduplication is handled with an in-memory set passed through the call, avoiding any risk of stale on-disk state surviving across pod restarts. Within each tarball, opt/kata path prefixes are stripped and absolute symlink / hard-link targets are rewritten to point at the resolved installation directory, correctly handling MULTI_INSTALL_SUFFIX.
