Locale override set to zh-CN but UI remains in English

Bug description After setting localeOverride = "zh-CN" in config.toml under [desktop], the Codex desktop UI remains in English. The setting is saved correctly but has no visible effect. Steps to reproduce 1. Open Codex desktop app settings 2. Change language to Chinese (zh-CN) 3. Confirm the setting is saved in ~/.codex/config.toml (localeOverride = "zh-CN") 4. Restart the app 5. UI is still in English Expected behavior UI should display in Chinese after selecting zh-CN. Environment - OS: Windows - Codex version: 0.136.0-alpha.2 - Config path: C:\Users\<user>\.codex\config.toml - Setting: [desktop] localeOverride = "zh-CN"
