feat: Go backend, enhanced search, new widgets, Docker deploy
Major changes: - Add Go backend (backend/) with microservices architecture - Enhanced master-agents-svc: reranker, content-classifier, stealth-crawler, proxy-manager, media-search, fastClassifier, language detection - New web-svc widgets: KnowledgeCard, ProductCard, ProfileCard, VideoCard, UnifiedCard, CardGallery, InlineImageGallery, SourcesPanel, RelatedQuestions - Improved discover-svc with discover-db integration - Docker deployment improvements (Caddyfile, vendor.sh, BUILD.md) - Library-svc: project_id schema migration - Remove deprecated finance-svc and travel-svc - Localization improvements across services Made-with: Cursor
