Subject: [PATCH] feat: add 301 redirects for old Serbian URLs to preserve SEO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Redirect old Serbian URLs (without /sr/ prefix) to new /sr/ URLs:
- / → /sr (301)
- /products → /sr/products (301)
- /about → /sr/about (301)
- /contact → /sr/contact (301)
- /checkout → /sr/checkout (301)

English URLs (/en/*) remain unchanged. This preserves SEO value
as Google treats 301 as permanent redirect passing ~90-99% PageRank.
