feat: Initialize News Engine Console project

Create comprehensive news pipeline management and monitoring system
with backend API structure and detailed implementation roadmap.

Core Features (7):
1. Keyword Management - Pipeline keyword CRUD and control
2. Pipeline Monitoring - Processing stats and utilization metrics
3. Pipeline Control - Step-wise start/stop and scheduling
4. Logging System - Pipeline status logs and error tracking
5. User Management - User CRUD with role-based access (Admin/Editor/Viewer)
6. Application Management - OAuth2/JWT-based Application CRUD
7. System Monitoring - Service health checks and resource monitoring

Technology Stack:
- Backend: FastAPI + Motor (MongoDB async) + Redis
- Frontend: React 18 + TypeScript + Material-UI v7 (planned)
- Auth: JWT + OAuth2
- Infrastructure: Docker + Kubernetes

Project Structure:
- backend/app/api/ - 5 API routers (keywords, pipelines, users, applications, monitoring)
- backend/app/core/ - Core configurations (config, database, auth)
- backend/app/models/ - Data models (planned)
- backend/app/services/ - Business logic (planned)
- backend/app/schemas/ - Pydantic schemas (planned)
- frontend/ - React application (planned)
- k8s/ - Kubernetes manifests (planned)

Documentation:
- README.md - Project overview, current status, API endpoints, DB schema
- TODO.md - Detailed implementation plan for next sessions

Current Status:
✅ Project structure initialized
✅ Backend basic configuration (config, database, auth)
✅ API router skeletons (5 routers)
✅ Requirements and environment setup
🚧 Models, services, and schemas pending
📋 Frontend implementation pending
📋 Docker and Kubernetes deployment pending

Next Steps (See TODO.md):
1. MongoDB schema and indexes
2. Pydantic schemas with validation
3. Service layer implementation
4. Redis integration
5. Login/authentication API
6. Frontend basic setup

This provides a solid foundation for building a comprehensive
news pipeline management console system.
