The Accept-Language header parsing was not correctly handling quality factors. When a browser sends "en-GB,de-DE;q=0.5", the expected behavior is to prefer English (q=1.0 by default) over German (q=0.5). The fix uses golang.org/x/text/language.ParseAcceptLanguage to properly parse and sort language preferences by quality factor. It also adds base language fallbacks (e.g., "en" for "en-GB") to ensure regional variants match their parent languages when no exact match exists.
