matcha v0.2.1

This is a hotfix release that resolves an import error introduced in v0.2.0 when installing matcha from PyPI.

Bug Fixes

Fix ModuleNotFoundError for utils module on pip install — Users who installed matcha via pip install matcha and ran matcha list (or any command) encountered a ModuleNotFoundError: No module named 'utils'. This happened because matcha/cli.py imported from a utils/ directory that is present in the source tree but not included as an installable package. The fix moves logger.py into the matcha package itself (matcha/logger.py) and updates the import accordingly.

pip install --upgrade matcha
