fix(packaging): bundle setuptools/_vendor for frozen pkg_resources

Setuptools 80+ pkg_resources imports jaraco.* and platformdirs after
adding setuptools/_vendor to sys.path. PyInstaller onefile did not ship
that tree, causing ModuleNotFoundError: jaraco at pyi_rth_pkgres.
Include the full _vendor directory as datas; add platformdirs to
hiddenimports. Applied to windows, linux, and macos specs.
