Pull Request Overview

This PR introduces a Redis-based Compare-And-Swap (CAS) broker implementation for the matcher system. The Redis CAS broker provides an alternative event distribution mechanism that uses Redis SET operations with polling instead of Redis Streams, offering simpler conflict resolution and reduced dependency complexity.

Key changes:

• Implementation of Redis CAS broker with polling-based event consumption
• Renaming of broker interfaces from EventBrokerInterface to Broker for consistency
• Comprehensive test coverage for the new Redis CAS broker including integration tests
