* feat(i18n): add Korean language support
- Add Korean (ko) translation files for all namespaces:
- common.json, auth.json, settings.json, sidebar.json, chat.json, codeEditor.json
- Register Korean locale in config.js and languages.js
- Follow translation guidelines:
- Keep technical terms in English (UI, API, Shell, Git, etc.)
- Use Korean phonetic for some terms (TaskMaster → 테스크마스터)
- Maintain concise translations to match English length where possible
