Allow bilingual / localized descriptions for built-in skills and slash commands

It would be very helpful if Claude Code allowed users to see (or override) the descriptions shown in the / command menu in their preferred language, in addition to English.

Currently, custom skills support arbitrary text in the description frontmatter field, so users can manually add bilingual text (e.g., "English description | Local language translation"). However, built-in skills/commands (e.g., code-review, verify, update-config, etc.) have hardcoded English descriptions that cannot be customized.

Suggestion:

• Allow a config option (e.g., in settings.json) to provide translated descriptions/overrides for built-in commands, shown alongside or instead of the English text in the / menu.
• Alternatively, extend the existing language setting (which currently only affects Claude's response language) to also localize the CLI menu/command descriptions, based on community-contributed translation files.

This would greatly improve usability for non-English-speaking users and teams.
