feat: markdown module

mdtidy's library is now tidy::markdown, with the same API: format,
format_with, check, Options and Preset. pulldown-cmark stays pinned
at 0.13.6, since its event ranges are part of the output. The
Preserve preset's ignore directive is tidy-ignore. Its tests run as
tidy's, and the semantics oracle reads TIDY_MARKDOWN_CORPUS.
