Research direction

The issue is in the `stat` command's handling of the `%N` format specifier. Look at the `format item` function in `src/uucore/src/lib/features/stat.rs` or similar file that processes format strings. Ensure that when outputting filenames containing special characters like newline, they are escaped using `$'\n'` syntax as GNU stat does. The reproduction steps are provided, so testing can be done by creating a file with a newline and running the stat command.
