Summary of Changes

This PR adds Russian language support, improves the translation system, and makes GitHub statistics/contributor data more reliable by introducing build-time fallbacks.

Internationalization (i18n)
Added complete Russian locale (ru.json) and registered Russian as a completed language in meta.json.
Added automatic locale generation scripts (generate-ru-locale.mjs, seed-ru-locale.mjs) with translation caching support.
Improved useTranslation to load locales dynamically and handle fallback languages more reliably.
Updated LanguageSwitcher to synchronize the document language attribute (lang) with the selected language.
Updated Tag component so tag names are translated through the i18n system.

GitHub Stats & Contributors
Added build-time GitHub data generation (scripts/github-stats.js).

Added cached fallback datasets:
githubStats.json
githubContributors.json

Created shared helper utilities (lib/githubStats.js) for loading GitHub stats/contributors with:
timeout handling
API fallback support
graceful failure behavior

Refactored:
GitHubHeaderBadge
ContributorsSection
About page

to use fallback data first and then refresh with live GitHub API data.

UI / Reliability Improvements
Replaced contributor avatars with a fallback strategy when GitHub avatar loading fails.
Added image styling improvements (object-fit: cover) for contributor avatars.
Added hydration warning suppression in layout.tsx to avoid client/server mismatch warnings.
Added missing translation keys for navigation items such as Home, About, Contribute, and Simulations.

Build Process
Updated build pipeline to generate GitHub stats automatically before next build.
Added google-translate-api-x dependency for locale generation workflows.

Reasons :-
Enable Russian localization across the site.
Reduce dependence on live GitHub API availability/rate limits.
Improve SSR hydration stability.
Ensure contributor and repository statistics remain visible even when GitHub requests fail.
