Move quickstart.md into docs site and add it to nav

Fixes the strict-mode docs build: docs/examples/index.md linked
../../quickstart.md, which lives outside the MkDocs docs_dir and can
never resolve. The guide is now part of the published site under
Getting Started, and the README link follows the file.

Verified locally with mkdocs build --strict: 0 warnings.
