The bezalel-vps-runner (act v0.2.11) fails in 1-6s because Node.js is
not in PATH of the default runner container, preventing any GitHub
Actions (actions/checkout, setup-uv, setup-node, etc.) from executing.
Add `container: catthehacker/ubuntu:act-22.04` to all workflow jobs.
This image is purpose-built for act runners and includes Node.js, git,
Python, npm, and other common CI tooling needed to run GitHub Actions.
Fixes#174
