📦 POETRY DEPENDENCY RESOLUTION
===============================

❌ Dependency conflict detected!

🔴 Conflict:
   requests (>=2.28) requires urllib3<2.0
   boto3 (>=1.34) requires urllib3>=2.0

💡 Solutions:
   1. poetry add "urllib3>=1.26.18,<2.0"
   2. poetry add "requests>=2.32.0" (urllib3 2.x 지원)
   3. 별도 환경에서 분리 실행

Recommended:
   poetry add "urllib3>=1.26.18,<2.0" --lock
