ci: make attw advisory (upstream crash), keep publint gating (#41)

@arethetypeswrong/cli crashes internally ("Cannot read properties of undefined
(reading 'filename')") on this package's ESM-only multi-subpath exports — across
versions and on a clean rebuild, unrelated to package content. publint validates
the exports are correct and stays gating; attw is downgraded to a warning so its
crash no longer fails CI. Revert once the upstream bug is fixed.
