Feature Request: Turkish (tr-TR) language support for Claude Code & Fathom companion

Summary

Claude Code currently supports 15 locales (de-DE, en-US, es-419, es-ES, fr-FR, hi-IN, id-ID, it-IT, ja-JP, ko-KR, pt-BR, etc.) but Turkish (tr-TR) is missing.

Additionally, the Fathom companion mascot has hardcoded English personality strings with no i18n support.

What I'd like

1. Turkish (tr-TR) locale file added to Claude Code's resources/ directory alongside existing locale JSONs
2. Fathom companion personality strings externalized to locale files so they can be localized
3. UI strings (menus, prompts, status messages) translated to Turkish

Why

Turkey has a growing developer community actively using Claude Code. Turkish language support would make the tool more accessible and improve the developer experience for Turkish-speaking users.

Current behavior

• Claude Code locale files: de-DE, en-US, en-XA, en-XB, es-419, es-ES, fr-FR, hi-IN, id-ID, it-IT, ja-JP, ko-KR, pt-BR — no tr-TR
• Fathom companion personality is hardcoded in .claude.json settings, not subject to i18n
• Only a basic tr.pak exists in Chromium layer, but no application-level Turkish strings

Environment

• Claude Code v2.1.92
• Windows 11 Pro
• PowerShell terminal
