Refactor codebase

- Remove unused pyproject.toml and uv.lock files (HuggingFace Spaces uses requirements.txt)
- Remove unused imports (Path, Any, Optional)
- Reorganize imports to follow standard order (stdlib, third-party)
- Remove unused api_key parameter from create_demo function
- Pin anthropic version to >=0.38.0 in requirements.txt
