Add Clipboard HTML → Markdown tool

[rodrigogiraoserrao]

Motivation

• Provide a simple standalone tool that lets users paste rich HTML from the clipboard and get equivalent Markdown, with one-click paste and copy actions.

Description

• Add html-to-markdown-clipboard.html, a self-contained UI that uses the turndown CDN to convert HTML to Markdown and exposes Paste from clipboard and Copy Markdown buttons that use navigator.clipboard.read and navigator.clipboard.writeText respectively.
• Add html-to-markdown-clipboard.docs.md with a short description for the new tool.

Testing

• Started a static server with python -m http.server and served the new HTML file successfully.
• Attempted an automated Playwright script to fill the input and take a screenshot, but the Playwright run timed out / failed to interact with the page; no pytest tests were executed.
