Patch Changes

• #16837 783c4a6 Thanks @jdevalk! - Improves <lastmod> accuracy in the sitemap index. Each <sitemap> entry in sitemap-index.xml is now stamped with the most recent lastmod of the URLs in the child sitemap it points to, instead of repeating a single global date on every entry. When a child sitemap has no per-URL lastmod, the entry falls back to the lastmod option as before. This gives search engines a per-file freshness signal, so they can tell which child sitemaps actually changed without refetching all of them.
