#474 Replace CI Pull request opened by donn This removes the technical debt-laden CI with a new one based on Nix and Volare. The CI uses Magic 8.3.515 and Volare 0.20.6 to build both sky130 and gf180mcu. A successful build is required for the CI to clear. This will run on all pushes and pull requests, and it takes about 30 minutes. In the event a new tag is pushed and the secret

BOT_GH_TOKEN

is specified, the result of the build is pushed to Volare as a pre-release. Pre-releases may be converted to full releases at the Volare maintainer's discretion. --- Incidentally, the reason macOS was picked is that the Mac runners, presently, have way more available storage than the Linux runners, especially if you delete the 8 billion versions of Xcode installed.
