Update ci.yml

Fixed the CI smoke import by installing the package runtime dependencies before the import check.

  What changed:

  - In ./.github/workflows/ci.yml, the Windows job now runs:
      - pip install -e . --no-build-isolation
      - before python -c "import metbit; print(metbit.__version__); print(metbit.backend_info())"

  Why this fixes it:

  - metbit imports numpy and other runtime packages at import time.
  - The CI job was only installing build tooling, so the smoke import failed immediately on missing dependencies.
