- Replace PluginManager.AllPlugins with GetAllLoadedPlugins()
- Replace PluginManager.NonGlobalPlugins with GetNonGlobalPlugins()
- Fix InitializePluginsAsync to pass IResultUpdateRegister parameter
- Fix QueryBuilder.Build to pass required 3 parameters
- Implement IResultUpdateRegister interface on MainViewModel
