release: v1.1.0 - Enhanced security, monitoring, and configuration management

Major Features:
- Add comprehensive architecture documentation (ARCHITECTURE.md)
- Implement centralized environment variable validation (src/config/env.js)
- Add Redis support for distributed rate limiting (src/config/redis.js)
- Add metrics collection endpoint and middleware (src/routes/metrics.js, src/middleware/metrics.js)
- Implement query security middleware to prevent SQL injection (src/middleware/querySecurity.js)
- Add structured error handling system (src/errors/index.js)
- Add body parser middleware for request validation (src/middleware/bodyParser.js)

Infrastructure & Testing:
- Add Jest testing framework with test setup and initial test suites
- Add test coverage for error handling and validation middleware
- Add authentication route tests
- Update Docker Compose configurations for development and production

Security & Performance:
- Enhance OAuth2 client implementation
- Improve rate limiting with Redis fallback support
- Strengthen query endpoint security
- Update authentication and health check endpoints

Documentation & Configuration:
- Update README with new features and improved setup instructions
- Enhance OpenAPI documentation with new endpoints and schemas
- Update .env.example with new configuration options
- Improve .gitignore for better security

Dependencies:
- Add ioredis for Redis connectivity
