* feat(docs): enable i18n language selector
* docs(i18n): translate introduction page to English
* fix(i18n): fix language switching issue by always showing locale prefix

* refactor(i18n): make getLocalizedPath respect hideLocale config
* feat(i18n): fallback to default language when translation missing, keep URL unchanged
* feat(i18n): fix language loss in navigation and add language selector
- Set hideLocale to 'never' to always show language prefix
- Add localized-navigation.ts with useLocalizedRouter hook
- Update all navigation points to preserve language:
1. Tab navigation (already using getLocalizedPath)
2. Sidebar navigation (handled by Fumadocs)
3. Home/404 redirects (using getLocalizedPath)
4. MDX Redirect component (using useLocalizedRouter)
5. Old page redirects (updated not-found.tsx)
6. Document links (custom LocalizedLink component)
- Configure language selector in layout.config.tsx
- Add LOCALIZED_NAVIGATION.md documentation

* refactor(i18n): move redirects to middleware for SSR support
- Move old path redirects from client-side (not-found.tsx) to server-side (middleware.ts)
- Use 301 permanent redirects for better SEO
- Preserve language prefix in redirects
- Fix SSR issue caused by client-side redirects
* refactor(i18n): clean up not-found.tsx, remove duplicate redirect maps
- Remove duplicate exactMap and prefixMap (now in middleware)

- Always redirect to introduction page on 404
- Ensures no 404 pages are shown
