Job-level timeout-minutes is parsed but not enforced by this runner; only the runner's jobTimeout bounds a job. Also fixes the devshell coverage comment, the shellcheck job comment, an option description citing a script that is not in the repo, and comment file pointers that resolve to nothing.

# Nightly plus manual dispatch. The report is uploaded as an artifact rather
|

# ⚠️ The hour is deliberate: at the default job capacity of 1
|
|
# (`services.hyperhive.deploy.ci-runner.concurrency`) this job holds the
|
|
# runner for its whole run and everything else queues behind it.
|
|
#
|
|
# Separate from ci.yml because a `workflow_dispatch` trigger there fires every
|
|
# job in that file, and this must not run per pull request.
