Astro's sitemap integration emits /sitemap-index.xml + /sitemap-0.xml. Bing
Webmaster Tools and IndexNow probe /sitemap.xml literally, so a request
for the canonical name was 404'ing. Two changes:
- astro.config.mjs: add a 301 redirect /sitemap.xml → /sitemap-index.xml
(alongside the existing / → /en/ redirect)
- public/robots.txt: list both Sitemap URLs so any crawler that reads
robots.txt finds an entry it can use directly
After production redeploys (`docker compose up -d --build`), submit
https://nibiru-framework.com/sitemap.xml in Bing Webmaster Tools — it'll
follow the 301 and ingest the index.
