Feature request: Localization (i18n) support for extension UI — Japanese

Summary

The Claude Code VSCode extension UI (Modes panel, status indicators, buttons, tooltips, etc.) is currently English-only. Please add localization support so non-English users can use the extension in their native language.

Specific request

• Provide package.nls.ja.json (and other locales) alongside package.nls.json
• Localize user-facing strings in the Modes panel such as:
• "Ask before edits" / "Edit automatically" / "Plan mode" / "Effort"
• Descriptions like "Claude will ask for approval before making each edit"
• "to switch" hint text
• Respect the VSCode locale setting (e.g., when locale.json is set to ja, the extension should display Japanese)

Motivation

VSCode itself supports Japanese via the official language pack (MS-CEINTL.vscode-language-pack-ja), but the Claude Code extension remains in English, which creates a jarring mixed-language experience for Japanese users. Many Japanese developers use Claude Code daily and would benefit greatly from a localized UI.

Environment

• OS: Windows 11
• VSCode: with locale: ja configured
• Extension: anthropic.claude-code (latest)
