Fix compilation errors in iOS project

[codegen-sh]

This PR fixes several compilation errors in the iOS project:

1. Fixed ambiguous CommandResult type by renaming it to AppCommandResult in AppContextManager.swift and updating all references
2. Fixed DebuggerViewController by renaming tabBarController to debugTabBarController to avoid conflicts
3. Fixed AIViewController by adding proper frame parameter to UITableView initialization and implementing ViewControllerRefreshable protocol
4. Fixed unused variable warning in TerminalButtonManager.swift
5. Fixed DispatchQueue.main.async syntax in ChatViewController.swift

All these changes maintain the original functionality while resolving the compilation errors.
