Add Clipboard HTML → Markdown tool (#111)

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.

Add VS Code to Beehiiv conversion tool (#109)

Motivation

• Provide a small standalone HTML tool that converts Markdown pasted from VS Code into the rich HTML Beehiiv expects so it can be pasted directly into the Beehiiv editor.
• Support common Markdown features such as links, bold, italics, inline code, and fenced code blocks while preserving language classes for syntax highlighting.
• Offer a one-click Copy to clipboard action that writes both text/plain and text/html clipboard representations for seamless pasting into Beehiiv.

Description

• Add vscode-to-beehiiv.html implementing a UI with a Markdown input, Beehiiv HTML preview, and an output textarea, and add vscode-to-beehiiv.docs.md documenting the tool.
• Convert Markdown to HTML with marked.parse, parse it with DOMParser, and assemble Beehiiv-ready blocks that include data-id, optional data-pm-slice on the first paragraph, and a style string (BLOCK_STYLE).
• Normalize anchors to include target="_blank", rel="noopener noreferrer nofollow", and class="link", and normalize code classes by replacing language-py with language-python.
• Implement clipboard copy via navigator.clipboard.write with a ClipboardItem containing both text/html and text/plain, and handle paste events by reading text/plain from the clipboard into the editor.

Testing

• Started a local server with python -m http.server 8000 to serve the new HTML file, which successfully began serving files.
• Attempted to use Playwright to open the page and capture a screenshot, but the Playwright runs timed out and did not complete (failed).
• No other automated tests were executed against the static HTML tool; clipboard interaction could not be validated due to browser automation timeouts.

Fix beehiiv heading conversion (#110)

• Beehiiv expects real heading tags with anchor metadata instead of paragraphs containing bold text for headings.
• The previous conversion produced <p><strong>…</strong></p> for #/##/... headings, which did not match Beehiiv rich media output.

Description

• Update vscode-to-beehiiv.html to emit actual heading tags (<h1>–<h6>) instead of paragraph wrappers for markdown headings.
• Add HEADING_STYLE derived from BLOCK_STYLE and set Beehiiv-specific attributes on headings: data-id, id, data-anchor, data-anchor-title, data-anchor-id, data-anchor-title-sync, and data-anchor-id-sync.
• Preserve heading content with innerHTML and set data-pm-slice="1 1 []" on the first block to match Beehiiv slice behavior.
• Keep existing handling for paragraphs, lists, code blocks, and link attributes unchanged.
