feat: add Copy Text and Download .docx buttons to response window

- Copy Text: copies raw markdown to clipboard with visual feedback
- Download .docx: converts markdown to a properly formatted Word
  document using the docx library (headings, bold/italic, lists,
  tables, blockquotes, links, horizontal rules)
- Both buttons appear below the response article after streaming ends
- docx/file-saver are lazy-loaded (dynamic import) so they don't
  bloat the initial bundle (~308 KB main vs ~407 KB docx chunk)
