Fix copy-for-LLM button to preserve markdown

[mmurrs]

Summary

• The "Copy for LLM" button was using article.innerText which stripped all formatting — headings, code blocks, links, tables, lists — producing useless plain text
• Replaced with turndown library for proper HTML-to-markdown conversion
• Added custom rules for Docusaurus admonitions, fenced code blocks with language annotations, and stripping UI chrome (copy buttons, the LLM button itself)

Test plan

• Click "Copy for LLM" on a page with code blocks — verify they appear as fenced markdown with language tags
• Click on a page with headings, links, lists, tables — verify all formatting preserved
• Click on a page with admonitions (tip/note/warning) — verify they appear as labeled blockquotes
• Verify the copied text does NOT include "Copy" buttons or "Copy for LLM" button text
• Paste into an LLM context window and verify it parses correctly
