CVE-2026-53475: Archive Chained Symlink Traversal

Archive extraction without resolving symlinks in the destination parent directories can lead to chained symlink traversal (Tar Slip) vulnerabilities. By placing a directory symlink in the archive and modifying content through it, an attacker can escape the target directory constraint even if standard path validations are performed. Call `filepath.EvalSymlink
