Feature Request: Localize UI labels (e.g. 'Recents') to Japanese

Feature Request: UI Localization / Japanese Language Support

Summary:
The left sidebar label "Recents" (and other UI labels) should be displayed in Japanese when the system language is set to Japanese.

Current behavior:
All UI labels in Claude Code are in English regardless of the OS language setting.

Expected behavior:
UI labels such as "Recents" in the left sidebar should be localized to Japanese (e.g., 「最近」 or 「履歴」) when the system language is Japanese.

User environment:

• macOS (Japanese)
• Claude Code desktop app

Additional context:
Japanese users would benefit from a localized UI. At minimum, the left sidebar labels should follow the OS language setting.
