Add a `noindex` param to page front matter to block Google indexing for specific pages or directories. This is useful for avoiding duplicate content in search results or preventing indexing of pages that shouldn't appear in search engines. - Adjust `head.html` for optional `noindex` param (default: false) - Document usage in `configuration.md` and clarify Flexsearch section
