Codex desktop app: Simplified Chinese mistranslates Plan mode as "套餐"

Description

In the Codex desktop app, the Plan mode output header is localized as 套餐 in Simplified Chinese. In this context, "Plan" means an execution/task plan, not a subscription/package plan, so 套餐 is misleading.

The same localization issue was previously reported for the VS Code extension in #10609. This report is for the desktop app.

Suggested labels, if maintainers agree: bug, app, plan.

Environment

• Variant: Codex desktop app
• App version: 26.623.101652, build 4674
• Bundled CLI: codex-cli 0.142.5
• Platform: macOS 15.7.7, build 24G720, arm64
• Locale/UI language: Simplified Chinese / zh-CN behavior observed in the UI

Steps to reproduce

1. Open the Codex desktop app.
2. Use the Simplified Chinese UI / zh-CN locale.
3. Ask Codex to create a plan so a Plan mode result card is rendered.
4. Observe the label above the generated plan.

Actual behavior

The card header label displays 套餐.

Expected behavior

The label should display 计划 or remain Plan.

Evidence

The current local desktop session shows the generated plan card header rendered as 套餐 above a Chinese-language plan titled "Surge Tailnet DNS 与路由绕过修改计划". I am not attaching the full screenshot because it includes unrelated conversation content; the relevant visible text is the header label 套餐.
