feat: implement complete Phase 2 frontend foundation with React 18

Major milestone: Frontend implementation complete for Shattered Void MMO

FRONTEND IMPLEMENTATION:
- React 18 + TypeScript + Vite development environment
- Tailwind CSS with custom dark theme for sci-fi aesthetic
- Zustand state management with authentication persistence
- Socket.io WebSocket client with auto-reconnection
- Protected routing with authentication guards
- Responsive design with mobile-first approach

AUTHENTICATION SYSTEM:
- Login/register forms with comprehensive validation
- JWT token management with localStorage persistence
- Password strength validation and user feedback
- Protected routes and authentication guards

CORE GAME INTERFACE:
- Colony management dashboard with real-time updates
- Resource display with live production tracking
- WebSocket integration for real-time game events
- Navigation with connection status indicator
- Toast notifications for user feedback

BACKEND ENHANCEMENTS:
- Complete Research System with technology tree (23 technologies)
- Fleet Management System with ship designs and movement
- Enhanced Authentication with email verification and password reset
- Complete game tick integration for all systems
- Advanced WebSocket events for real-time updates

ARCHITECTURE FEATURES:
- Type-safe TypeScript throughout
- Component-based architecture with reusable UI elements
- API client with request/response interceptors
- Error handling and loading states
- Performance optimized builds with code splitting

Phase 2 Status: Frontend foundation complete (Week 1-2 objectives met)
Ready for: Colony management, fleet operations, research interface
Next: Enhanced gameplay features and admin interface
