Feature request: Russian UI localization (i18n support for the desktop app)

What feature would you like to see?

Russian localization of the Kimi desktop app interface (menus, buttons, settings, dialogs).

What I checked (Kimi desktop, Windows, current version):

1. There is no language/locale selector anywhere in Settings, and the app config (%APPDATA%\kimi-desktop\daimon-share\daimon\config.json) contains no language option.
2. The app bundle (resources/app.asar) contains no i18n resource files — UI strings appear to be hardcoded, with no localization framework in place. The only language-related entries inside the bundle are Monaco editor's syntax modules, and the locales/*.pak files (including ru.pak) are Chromium's built-in locales, not app UI strings.

Request:

1. Introduce an i18n framework (e.g. i18next / react-intl) and extract UI strings into locale resource files.
2. Add Russian (ru-RU) as a supported UI language.
3. Add a language selector in Settings, with "follow system" as the default.

Why it matters:

• Russian is spoken by ~250 million people and is a top-10 language by number of Internet users.
• The Kimi agent itself already converses fluently in Russian — the UI is the only untranslated layer.
• Once string extraction is done, the community can help with translation. I'd be glad to contribute as a translator/proofreader.

Additional information

Happy to provide version info or screenshots of the current UI if helpful. If the desktop app lives in a different tracker, please point me to the right place — thank you!

Start by confirming whether the Kimi desktop app source and Settings UI are in this repository or a different tracker. Inspect the current config path and app bundle described in the issue, then map where UI strings and language settings are implemented. Done means locale resources, ru-RU support, and a Settings selector with follow-system as the default.
