  SEO and AEO head additions for the TRACE conformance suite.

  1. The homepage <title> is overridden. Material falls back to site_name when a
     page has no front-matter title, which left the homepage titled "TRACE
     Tests". Front matter is not an option: docs_dir is the repository root, so
     README.md is also the GitHub landing page and YAML would render as noise
     there.

  2. Open Graph and Twitter meta, so links produce a card instead of a bare URL,
     plus JSON-LD so answer engines can model what this suite is.

  Asset paths derive from config.site_url. Do not hardcode them: assets are
  served under /docs/assets/ here because docs_dir is the repository root and
  CI copies docs/ into the build directory. That differs between sibling
  repositories, and a hardcoded path is how cMCP shipped a broken card.
