Module v2

Version 2 provider architecture Provider V2 - Next generation provider architecture

This module defines the improved provider architecture that aligns with the consolidated WebSocket implementation using MessageHandler pattern.

Key improvements over V1:

• Separation of concerns: REST APIs vs real-time streaming
• Event-driven architecture using callbacks instead of channels
• Integration with WebSocketClient/MessageHandler pattern
• Cleaner trait boundaries and reduced coupling
• Better error handling and resource management
