fix(pacquet): satisfy perfectionist dylint lints

- Use raw strings for the shlex escape and the no-placeholder display /
  help messages that contained `\"` escapes (perfectionist::prefer_raw_string).
- Add the trailing comma to the multi-line format! in the run listing
  (perfectionist::macro_trailing_comma).
