Greptile Summary

This PR extends the Check MDX safety CI step (introduced in #282) to also scan the fern/ directory and *.mdx files for non-self-closing <img> tags, alongside the existing docs/*.md coverage. It also adds inline comments explaining the intentional design choices (single-step, single-line grep).

Confidence Score: 5/5

Safe to merge — a minimal, focused CI improvement with no production impact.

The only finding is a P2 style suggestion about || true masking grep errors, which does not affect correctness in practice since fern/ is always present in the repo. All logic (regex, --include flags, directory arguments) is correct.

No files require special attention.
