fetch_graalvm_version now returns a tuple of (version, amd64_sha, aarch64_sha), so the name is misleading and can cause callers to assume it only returns the version. Consider renaming it to reflect the full payload (e.g., fetch_graalvm_release_info / fetch_graalvm_checksums) or returning a small dict/dataclass for clarity.
