WebSocket Message Ordering & State Synchronization #502

@Ayaanshaikh12243

Description

@Ayaanshaikh12243

Location: [index.js

Issue: Race conditions exist in collaborative editing when multiple users send updates simultaneously
Problem: Message sequence numbers are incremented before sending but no guarantee of ordered delivery over unreliable networks
Impact: Users see different code versions, collaborative edits get lost or duplicated
Root Cause: messageSequence relies on client-side ordering without server-side validation of order
Scenario: User A sends code change, User B sends execution command - can arrive out of order causing execution of wrong code
