Permission prompt dialogs not localized (always shown in English) despite VS Code locale set to Japanese

Description
Permission confirmation dialogs (e.g. "Allow reading from <path>?", "Yes", "No", "Tell Claude what to do instead") are always displayed in English, even when VS Code's display language is set to Japanese.

Environment

• VS Code locale (argv.json): ja-JP
• Japanese Language Pack extension installed (ms-ceintl.vscode-language-pack-ja)
• Claude Code config: language=japanese

Expected behavior
Permission prompt UI text should follow VS Code's configured display language (or the Claude Code language config setting), consistent with how the assistant's own responses are localized.

Actual behavior
The permission dialog UI (Allow/Deny/Yes/No/etc.) remains hardcoded in English regardless of locale settings
