feat(v3.2): CI/CD config + Python bindings setup

- Add .gitea/workflows/build.yml (build, test, docs, python binding CI)
- Add root pyproject.toml + setup.py (CMake-based pip install)
- Add root vde/__init__.py (Python package entry point)
- Update README: CI badge, version 3.2.0, Python install instructions
- Bump project version to 3.2.0 across CMakeLists.txt, python/setup.py, python/vde/__init__.py
- Add build_py/ to .gitignore
