Push-notify search engines (Bing, Yandex, Seznam, Naver) when content
changes instead of waiting for sitemap crawls. Especially valuable for
batch article publishing and supplier directory updates.
- Add INDEXNOW_KEY config var and key verification route
- New seo/_indexnow.py: async fire-and-forget POST to IndexNow API
- notify_indexnow() wrapper in sitemap.py expands paths to all lang variants
- Integrated at all article publish/unpublish/edit and supplier create points
- Bulk operations batch all URLs into a single IndexNow request
- Skips silently when key is empty (dev environments)
