Feature request: Auto-generated session titles should respect language settings

Summary

Auto-generated session/tab titles are always in English kebab-case, regardless of the user's language setting or conversation language. For non-English users, titles should respect their language preference.

Current behavior

generateSessionName in cli.js hardcodes an English-only system prompt:

Generate a short kebab-case name (2-4 words) that captures the main topic...
Examples: "fix-login-bug", "add-auth-feature"...

This ignores:

• The language setting in settings.json
• The language of the conversation content
• The fr9() language injection used in the main conversation system prompt

Expected behavior

Title generation should respect the user's language setting. If settings.language is set (e.g., "Japanese"), the generated title should be in that language.

Suggested fix

Pass the user's language setting into the systemPrompt of the generateSessionName → cf() call, similar to how fr9($.language) is already injected into the main conversation system prompt.

Environment

• Claude Code v2.1.89 (VSCode extension)
• Windows 10
• User language: Japanese
