BIT-PYTHON-MIN-2026-11940 tarfile extraction filter bypass allows escaping the destination directory

tarfile.extractall with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the hardlink's shallower...
