feat: monorepo structure with Django backend, React frontend, and Expo mobile app

- Backend: Django 5 + DRF with accounts, documents, collections, and reading apps - Custom User model with email-based auth, JWT via SimpleJWT - Full CRUD viewsets with ModelSerializer + DRF routers - pytest, Ruff, drf-spectacular (OpenAPI), whitenoise - Dockerfile for production deployment - Frontend: React 18 + TypeScript + Vite - Lazy-loaded routes with ProtectedRoute/PublicRoute guards - Auth context with useReducer, token refresh interceptor - Pages: Login, Register, Library, Document Detail, Reader, Collections, Settings - Dark theme, responsive grid layout, Vite proxy to Django backend - Mobile: Expo SDK 51 + React Native + Expo Router - File-based routing with login, register, and library screens - AsyncStorage for token persistence, token refresh interceptor - Shared API types via @cloud-reader/shared workspace package - Shared: TypeScript types (API responses, auth, documents, etc.) - CI/CD: 3 independent GitHub Actions pipelines (backend, frontend, mobile)
