Feature Request: Add WebSocket Support

[iamxvbaba]

Description: I would like to propose adding WebSocket support to the framework.

Motivation:

• Enable real-time bidirectional communication between client and server
• Support common use cases like live updates and chat functionality
• Enhance the framework's capabilities for modern web applications

Suggested Implementation:

• Add a WebSocket handler system
• Support both ws:// and wss:// protocols
• Provide basic connection management utilities
• Include simple examples for common WebSocket patterns
