fix(custom-ordering): preserve the trailing newline in reverse and number

cj/reverse-lines and cj/number-lines split the region on newlines without accounting for a trailing one, so it became a spurious empty element. Reversing "a\nb\n" floated that empty to the top ("\nb\na"), and numbering added a phantom final numbered line. Both now strip a trailing newline before splitting and reattach it after, matching cj/--arrayify, while preserving internal blank lines. Corrected the two tests that asserted the broken output.
