/*
 * App.jsx - Main Application Component with Session Protection System
 * 
 * SESSION PROTECTION SYSTEM OVERVIEW:
 * ===================================
 * 
 * Problem: Automatic project updates from WebSocket would refresh the sidebar and clear chat messages
 * during active conversations, creating a poor user experience.
 * 
 * Solution: Track "active sessions" and pause project updates during conversations.
 * 
 * How it works:
 * 1. When user sends message → session marked as "active" 
 * 2. Project updates are skipped while session is active
 * 3. When conversation completes/aborts → session marked as "inactive"
 * 4. Project updates resume normally
 * 
 * Handles both existing sessions (with real IDs) and new sessions (with temporary IDs).
