* i18n(ru): refine Russian localization against the zh-Hans source
Translate newly added UI strings and align existing Russian entries
with the authoritative Simplified Chinese (zh-Hans) source, since the
project is maintained by a Chinese-speaking author.
New strings (check-for-update flow):
- MsgCheckUpdateHasNewVersion, menuCheckOnly, menuNewUpdate,
MsgNotSupport, LvTestIpInfo
Correctness fixes (changed meaning):
- TbSettingsHysteriaBandwidth: restore upload/download order (Up/Dw)
- TbSettingsMixedConcurrencyCount: "multi-threaded" (was "multi-stage")
- TransportRequestHostTip4: "QUIC encryption method" (was "security")
- TransportPathTip3: "QUIC encryption key"
- TbDomesticDNS: "DNS for direct connections"
Terminology and clarity:
- Unify the alias field to one consistent term across all rule/profile
labels, distinct from the memo field
- allowInsecure -> "skip certificate verification" (+ cert-pinning ref)
- Restore details dropped from EN but present in zh-Hans: Port Hopping
range, pre-SOCKS split routing, optional / "may fail" hints
Consistency and cleanup:
- Orthography, transport names (httpupgrade, XHTTPObject),
move-to-top/bottom wording, trailing-space cleanup
Scope: ServiceLib/Resx/ResUI.ru.resx only. Technical abbreviations are
kept in English (LAN, UUID, MTU, TLS, ALPN, SNI, ...). Stale Chinese
strings vs. current behavior were judged case by case.
* i18n(ru): shorten update-check button labels to fit fixed-width buttons
The check-update window has two fixed-width (100px) buttons. The Russian
labels were faithful but too long, so both were truncated and looked almost
identical, hiding the difference between the two actions:
- the "Only Check" button only checks whether a newer version is available
- the "Check Update" button checks, downloads, installs and restarts
Shorten both so they fit the button and clearly distinguish check vs update.
Note: menuCheckUpdate is also reused as the default row placeholder in the
update list, which now shows the shorter label as well.
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.
