Support i18n for CLI permission prompts

Feature Request

The CLI permission prompts (e.g., "Do you want to proceed?", "Yes", "No") are hardcoded in English. It would be great to support localization/i18n for these UI texts based on user preference or system locale.

Use Case

As a Chinese-speaking user, I'd prefer to see permission prompts in Chinese (e.g., "是否继续？", "是", "否") to match the rest of my workflow where I communicate with Claude in Chinese.

Suggestion

• Allow users to configure the CLI language in settings
• Or auto-detect from system locale
