Replace `println!` calls on the results paths with `writeln!` on `io::stdout()` and propagate the `io::Error` to `main`, where `ErrorKind::BrokenPipe` is turned into a quiet `exit(0)`. This matches the conventional behavior of command-line tools when their output pipe is closed early (e.g. `hyperfine ... | head -n 0`), and fixes panics in all run-output paths: the per-benchmark header and results, the speed comparison summary, and `-`-style exports to stdout. The warnings and "Note" outputs to stderr are converted the same way. --------- Co-authored-by: Mathjk <Mathjk@users.noreply.github.com> Co-authored-by: David Peter <mail@david-peter.de>
