Introduce a small update-notification feature: add AppEvents.HasUpdateNotified event and have TaskManager publish it when update messages exist. Add localized resource key (menuNewUpdate) and expose it in the ResUI designer; update resource files for several languages. In the UI, add a New Update button in MainWindow.xaml, wire its click to the existing check-update handler, bind its visibility to a new BlNewUpdate property on MainWindowViewModel, and subscribe the viewmodel to the new event. Also reset the notification flag after showing the Check Update dialog.
Fetch and display tested server IP and country (with emoji) in speed tests. Adds CountryExtension for country->emoji mapping and a new IpInfoResult type; ConnectionHandler now retrieves/parses IP API results and GetRealPingTime signature adjusted. Models and entities (ProfileItemModel, ProfileExItem, SpeedTestResult) gain IpInfo fields; ProfileExManager can store test IP info. UI/UX updated: new IpInfo column in ProfilesView (desktop and Avalonia), ResUI resource strings for "IP Info", and EServerColName ordering supports IpInfo. SpeedtestService now captures IP info and forwards it to the view model via the update function.
Introduce a new "Check Only" feature: add CheckOnlyCmd to CheckUpdateViewModel with CheckOnlyTask that queries updates (via UpdateService.CheckHasUpdateOnly) for selected cores and reports results without performing updates. Wire up a new btnCheckOnly in both Desktop and Avalonia views and bind the command. Add localized menuCheckOnly entries to multiple .resx files and update ResUI.Designer. Also shorten the pre-release label to "Check for pre-release" in resource files.
Move many model classes into new sub-namespaces (ServiceLib.Models.CoreConfigs, ServiceLib.Models.Configs, ServiceLib.Models.Dto, ServiceLib.Models.Entities). Update GlobalUsings in ServiceLib, v2rayN.Desktop, v2rayN and add a tests GlobalUsings file to reference the new namespaces. Adjust static using directives in ClashApiManager and ClashProxiesViewModel to use ServiceLib.Models.Dto. This is a reorganization/rename of files and namespaces with no functional changes.
