Feature request: Localization / i18n support for UI labels (e.g. RECENTS → 最近)

Feature Request: Localization / i18n support

Description

UI labels such as RECENTS in the left sidebar are hardcoded in English inside the claude.exe binary. There is no way to translate or customize these labels via configuration files.

Proposed Solution

Please add internationalization (i18n) support so that UI labels can be displayed in the user's locale language.

For example:

• RECENTS → 最近 (Japanese)
• Other sidebar labels accordingly

Use Case

Japanese users (and users of other languages) would benefit from having the interface displayed in their native language.

Current Behavior

The text is embedded in the binary and cannot be changed through any config file.

Expected Behavior

UI labels respect the system locale or a configurable language setting.
