Markdown Formatter

Cleans up markdown files according to standard conventions: ATX headers, consistent list markers, fenced code blocks with language tags, proper spacing between elements. The modular approach is nice, you load only the resource you need (headers, lists, code blocks, links, or spacing). Built with security in mind since it treats file contents as untrusted data, which matters if you're processing community contributions or auto-generated docs. Includes a validation script and works alongside existing linters. Won't check spelling or validate URLs, just handles structural formatting. Best for standardizing README files, cleaning up documentation before commits, or enforcing house style across a docs repo.
