Fix GitHub Actions disk space issues

- Add centralized disk cleanup script (.github/scripts/free-disk-space.sh)
- Update root workflows to use script: test-build.yml, test-build-packages.yml, test-build-docker.yml, test-build-distributor.yml
- Update PR-build.yml to use script (Linux only)
- Frees ~20GB by removing .NET, Android SDK, Haskell, CodeQL tools
