feat: add single instance enforcement with TCP socket lock

Add single instance check using TCP listener on 127.0.0.1:53190 to prevent multiple application instances. Move AppState initialization into setup closure to include single_instance_lock field. Remove window close prevention and focus restoration handlers. Make main window non-resizable and non-maximizable.
