fix: disable automatic LICENSE file inclusion to fix PyPI upload

PyPI was rejecting uploads with error: "Invalid distribution metadata:
unrecognized or malformed field 'license-file'"

Root cause: Setuptools was automatically adding a deprecated
'license-file' metadata field when it detected a LICENSE file in the
repository root. PyPI no longer accepts this field format.

Solution: Explicitly set license-files = [] in [tool.setuptools] to
prevent automatic LICENSE file inclusion in wheel metadata.

The license is still properly declared via license = {text = "MIT"}
in the [project] section.

Also updated release workflow to build for all Python versions 3.8-3.14.
