fix: add docs pages to sitemap and enable prerendering in TanStack Start

- Include Fumadocs `source.getPages()` entries in `/sitemap.xml` alongside the home and module detail URLs; drop `changefreq` from all entries and make `priority` optional
- Enable `prerender` in `tanstackStart()` with `crawlLinks: false` so static pages are pre-built without a full crawl
