Split initI18n() into separate server/client initialization paths inspired by remix-i18next's architecture: - initI18nServer(lng): no LanguageDetector, per-request language from Accept-Language header - initI18nClient(): LanguageDetector reads <html lang> first to match server, then localStorage and navigator - detectLanguage(request): parses Accept-Language for best match Fixes rehydration errors caused by v26 removing initImmediate option (replaced with initAsync) and LanguageDetector running on the server where browser APIs don't exist. Also makes <html lang> dynamic instead of hardcoded "en". Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
