#
# Mirrors CI's "Check settings schema is up-to-date" step EXACTLY: regenerate,
# then fail if the committed artifact changed. Uses regenerate +
# `git status --porcelain` (NOT the generator's --check, which was reverted
# from main by #7031 — after merge this runs against main's generator, which
# ignores args and would make --check fail-open). Stale schemas are invisible
# to build/typecheck/lint/vitest.
#
# On failure: prints the diff, restores the schema file, writes
# `outcome=failed` to $GITHUB_OUTPUT (when set, matching the calling step's
# contract), and exits 1.
