rm: fix rustfmt, cspell, and clippy CI failures

- Run rustfmt to fix formatting in safe_remove_dir_recursive_impl
- Replace British English spellings with American English in comments
  (materialising→materializing, minimising→minimizing, amortised→amortized,
   initialisation→initialization, behaviour→behavior)
- Fix clippy: use inline format arg in panic! in safe_traversal test
- Add technical terms to cspell jargon dictionary:
  EMFILE, ENFILE, ENOMEM, NOFILE, getdents, btrfs, diriter, readdir
