ProseMirror schema (headings 1-4, lists incl. task lists, blockquote, code block, tables via prosemirror-tables, images, hard breaks; bold/ italic/code/strikethrough/link marks) plus docToMarkdown, markdownToDoc, docToPlainText, docToHtml, and extractOutline built on it. Markdown parsing extends markdown-it's default preset with a token-stream transform for GFM task lists and table-cell paragraph wrapping. docToHtml hand-rolls escaping and link-protocol allowlisting with zero DOM dependencies, so it runs in the API/collab server as well as the browser. Node names `wikilink` and `plugin_block` are reserved for later stories. Closes #24
