What

Add internationalization (i18n) support to the Codex desktop app, starting with Simplified Chinese (zh-CN) localization.

Why

Many developers in China and Chinese-speaking regions use Codex daily but the UI is only available in English. This creates a significant barrier to entry and reduces productivity for non-English speakers.

Scope

Menu bar items (File, Edit, View, etc.)
Sidebar panels (Threads, Projects, Settings)
Dialogs and confirmation messages
Error messages and notifications
Onboarding/welcome screens
All other visible UI strings

Implementation Suggestions

Extract all UI strings into a localization layer (e.g., JSON translation files)
Detect system locale or respect localeOverride in config.toml
Start with zh-CN, then expand to other languages
Community-contributed translations via GitHub are welcome

Config.toml Reference

The config.toml already has a [desktop] section with localeOverride = "zh-CN", suggesting partial localization infrastructure may already exist.

Thanks for considering this feature!
