fix: run workspace run.py via pre-baked venv instead of installing

pip3 and uv are not reliably on PATH in the pre-built container because
apt-get autoremove stripped python3-pip during image build. The uv venv
created at image-build time already has all dependencies; pointing its
Python directly at /workspace/run.py tests the current branch without
needing any install step.
