fix(ci): exclude pip/setuptools from license inventory to prevent version drift

generate_license_list.py was including pip itself in the output. pip version
differs between CI and local environments (25.1.1 vs 26.0.1), causing the
license check to fail with every pip upgrade in either environment.
Exclude pip, setuptools, wheel, and distribute — they are installer
infrastructure, not project dependencies.
