-- Move `license-files` from `[project]` to `[tool.setuptools]`.
-- FreeBSD's setuptools does not yet recognize `license-files` under
-- `[project]`, which causes `ValueError: invalid pyproject.toml config: project`.
-- This preserves the license file list while using the setuptools-specific
-- configuration section supported by the installed version.
