Proposal: Add Simplified Chinese (zh-CN) localization

[Jill-Stingray-L]

I'd like to contribute Simplified Chinese (zh-CN) localization for Codex Usage Widget.
I noticed that user-facing strings are currently hard-coded in XAML/C# and there does not appear to be an existing localization layer.
My proposed scope is:

• Extract user-facing English strings into standard .NET localization resources.
• Keep English as the default/fallback language.
• Add a zh-CN resource file.
• Localize the main widget, tray/context menus, setup dialogs, tooltips, status text, and other user-facing strings.
• Avoid introducing external dependencies.
  For language selection, would you prefer:

1. following the Windows/system UI culture automatically, or
2. an explicit language setting in the application?
   I'm happy to implement the localization infrastructure and provide the initial Chinese translation.

Hey @Jill-Stingray-L , thank you so much for wanting to contribute to the widget! I'd be more than happy for you to translate it into Simplified Chinese.

I’ve just finished a UI refactor that adds a settings window with all the widget options, and I think that would be the perfect place for the language selector.

I like your proposed scope. The goal is for the widget to detect the Windows language and select it automatically, with English always used as the fallback. Users should also be able to change the language manually in the settings whenever they want.

So, to answer your question: both. 😅
