check / check (pull_request) Failing after 1s
check.yml ran only on push to main and pull_request against main. Under the current workflow every unit is a PR based on next, and next is pushed to on each squash-merge, so neither got a CI run; the milestone PR from next to main was the first place a broken next would surface. Add next to both the push and pull_request branch lists so unit PRs and next itself are checked. The workflow is otherwise unchanged: same pinned actions/checkout sha, same script/cibuild step. README's Entrypoints section and TODO.md's log record where CI now runs. Model: opus-4-8
