What issue are you seeing?

When the Codex App language is set to Japanese, the labels for Staged and Unstaged appear to be reversed in the diff scope selector.

In English, the selector shows Unstaged and Staged correctly.

In Japanese, the option corresponding to Unstaged is shown as ステージ済み, and the option corresponding to Staged is shown as 未ステージ.

This makes the UI misleading because the translated labels indicate the opposite Git state from the actual one.

What steps can reproduce the bug?

1. Open the Codex App.
2. Set the app language to Japanese.
3. Open a repository where the diff scope selector is visible.
4. Open the diff scope dropdown near the top-left of the diff view.
5. Compare the Japanese labels with the English labels for the same UI.
6. Observe that Staged and Unstaged are translated in the opposite way.

What is the expected behavior?

Staged should be translated as ステージ済み.
Unstaged should be translated as 未ステージ.
The Japanese labels should match the actual Git state and the English UI.

Additional information

The issue appears to be specific to the Japanese localization.
I have screenshots comparing the English and Japanese UI.
The affected UI is the diff scope selector in the Codex App.
