openpreflight: CI without the control plane

Field notes

The documented workflow separates the fast webhook response from the slower worker job: validation and enqueueing happen within a ten-second window, followed by token minting, detached checkout, and timed steps. Pipelines can use Node defaults from package.json, binding overrides, or an optional runtime such as node:24. The example private pull request reports install, test, and build stages separately, while full logs remain outside the truncated GitHub Check Run tail.
