Create Socket.IO Middleware Pipeline

[underscorekadji]

Problem Description

Socket.IO event handling currently lacks a proper middleware system, making it difficult to implement cross-cutting concerns like authentication, validation, logging, and rate limiting. We need to create a robust middleware pipeline for Socket.IO events.

Acceptance Criteria

• Create middleware interface and pipeline system for Socket.IO events
• Implement authentication middleware for socket connections
• Add request validation middleware for socket events
• Create rate limiting middleware to prevent abuse
• Implement logging middleware for all socket events
• Add error handling middleware with proper error responses
• Create room authorization middleware
• Add performance monitoring middleware for socket operations

Technical Details

• Create ISocketMiddleware interface with execute method
• Implement middleware pipeline that processes events in order
• Add authentication middleware that validates user sessions/cookies
• Create validation middleware using existing Zod schemas
• Implement rate limiting using Redis for distributed rate limiting
• Add structured logging for all socket events and errors
• Create authorization middleware for room-specific permissions
• Implement middleware registration system with dependency injection

Estimate: 4 story points

This will provide robust Socket.IO event handling with proper security and monitoring.
