fix(ci): split Windows CI into unit tests (pip) + install.bat smoke test

Unit tests and integration tests use pip install -e (reliable).
Separate test-windows-install-bat job validates install.bat runs
and produces a working install. This avoids the PyPI cache issue
where install.bat picks up the old published version.
