Application state and data structures.

This module contains the core data structures for managing the application state, including user data, messages, message history, UI state, and connection status.

Key Types

• App - Main application state
• ConversationView - Per-peer message history with lazy loading
• Tab - UI tab navigation
• User - User information
• Message - Chat message data

Message History
