Show HN: Markdown Cleaner – clean AI-generated Markdown before pasting

If you ever paste AI-generated markdown into Google Docs (using the 'Paste as Markdown' option), you might have noticed that the formatting is not always perfect.

- Headings are often too deep: the top level headings use heading 2.

- Links are often long and ugly, which is annoying when they appear within the body of the document.

- Bulleted lists often use hyphens instead of asterisks (*) which means you get hyphens as bullets instead of circles/dots.
