Permission prompts (Yes/No) should respect the Language setting

Summary

When the Language setting is configured to a non-English language (e.g., Japanese) via /config, only the AI's responses are localized. The CLI UI elements — particularly the tool permission prompts ("Allow?", "Yes / No") — remain in English.

Expected behavior

All user-facing UI text, including permission prompts, should respect the Language setting configured in /config.

Current behavior

• AI responses: Correctly displayed in the configured language
• Permission prompts (Yes/No): Always displayed in English regardless of the Language setting

Motivation

Users who configure a non-English language likely prefer their entire interface in that language, not just the AI responses. This is especially important for accessibility and usability in non-English-speaking regions.

Environment

• Claude Code CLI
• Language setting: Japanese
