Drop markdown_to_pdf MCP surface, implementation, tests, and md-to-pdf dependency.
Roles that still list markdown_to_pdf must be cleaned before startup.

Teachers need ad-hoc Markdown → PDF. Ship an MCP tool powered by
md-to-pdf (Marked + headless Chrome) so remote images/CSS work, with
workspace-scoped basedir, front-matter stripped so untrusted markdown
cannot override dest/basedir/launch options, and MathJax for $/$ math.
Also include WebFetch and WebSearch in the unrestricted role tool
surface by default. Deploy skips Puppeteer's browser download and
expects a host Chrome/Chromium (PUPPETEER_EXECUTABLE_PATH / CHROME_PATH).
