feat: initial blog engine with multi-language, profile, and role system
- Gin + GORM + Tailwind CSS blog engine - OS-aware config (Linux /etc/blog_go/, Windows ./win/etc/blog_go/) - SQLite by default, MySQL support via config - Auto-migrate database + seed admin user on first run - Session-based auth (login/logout) - i18n: Chinese/English with auto-detect + manual switch - Avatar dropdown nav with click-to-toggle menu - Profile page: avatar upload, edit info, change password - Role system: admin (full access) and author (profile only) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
