Problem

The check CI job fails on every PR because CONTRIBUTING.md doesn't pass oxfmt --check. Since CI runs against the merge commit (PR branch merged into main), the unformatted CONTRIBUTING.md from main is always included and causes the format:check step to fail.

Example from PR #29031:

CONTRIBUTING.md (179ms)

Format issues found in above 1 files. Run without `--check` to fix.
Finished in 2582ms on 5727 files using 20 threads.
ELIFECYCLE  Command failed with exit code 1.

Details

• oxfmt version: 0.35.0 (same in CI and locally)
• The file passes oxfmt --check locally on Linux — this may be a platform-specific difference (Ubuntu 24.04 in CI vs other distros locally), or a shallow-clone artifact from the CI checkout
• The format:check step runs before tsgo, lint, etc., so this blocks all downstream checks from even running

Fix

Run oxfmt --write on CONTRIBUTING.md in the CI environment and commit the result, or investigate why the file formats differently on the CI runner.
