chore: adopt the new AIS test into the explicit formatting scope

scripts/format.mjs skips *.test.mjs during runtime discovery, so a test
added under a discovered root is never seen by format:check until it is
listed in scripts/format-scope.json — which is what CODE-BOUNDARIES.md
means by adding tests to the explicit list as they are adopted. The file
went in unformatted and the check stayed green, hiding it.

Listed and formatted; format:check now covers 917 files instead of 916.
