 * Preprocess TipTap HTML for odf-kit compatibility:
 * - Convert task lists to standard lists with checkbox text prefixes
 * - Replace <img> tags with warning text (odf-kit v1 skips images)
 * - Convert callouts (<aside>) to blockquotes
 * - Convert Twitter embeds to links
 * - Convert iframes (YouTube, SoundCloud, etc.) to links
 * - Strip TipTap-specific data attributes
 * - Convert void elements to self-closing XHTML for the XML parser
