Notes

Problem Context:
The "SuperClaude 완전 한국어 가이드" (Complete Korean Guide) section in README-kr.md was pointing to English documentation, causing Korean users to be redirected to English docs instead of Korean translations.

Alignment with Other Languages:
This fix aligns the Korean README with the existing patterns used in:

• Chinese README (README-zh.md → docs/user-guide-zh/)
• Japanese README (README-ja.md → docs/user-guide-jp/)
