The e2e reusable workflow defaulted to github.ref, which on
pull_request events is refs/pull/N/merge. GitHub does not compute
that ref when the PR has conflicts or before the merge commit is
ready, causing actions/checkout to fail with "couldn't find remote
ref refs/pull/N/merge" for reasons unrelated to the code.
Pass github.event.pull_request.head.sha from pr.yml so e2e checks
out the PR head directly.
Motivating failure: https://github.com/stablyai/orca/actions/runs/24768962365
Seen on #937.
The default oxlint output buries filenames in multi-line blocks, making
CI errors like "File has too many lines" hard to diagnose. The github
format produces ::error annotations with file paths front and center.
