Fix Windows dependency installation in CI

- Use pip install -e '.[dev]' to install all dependencies
- This installs both runtime deps (click, pyyaml, python-dotenv)
  and dev deps (pytest, pytest-cov, etc.) in one command
- Fixes ModuleNotFoundError: No module named 'click' on Windows
- Ensures consistent dependency installation across platforms
