REFACTOR: Break ChatViewModel into smaller specialized files
- Created ChatState.kt for centralized state management - Created DataManager.kt for persistence operations - Created MessageManager.kt for message handling and deduplication - Created ChannelManager.kt for channel operations and encryption - Created PrivateChatManager.kt for private chat functionality - Created CommandProcessor.kt for IRC-style command processing ChatViewModel.kt reduced from 1000+ lines to ~300 lines while maintaining 100% functionality. All existing functionality preserved, just better organized.
