Each bats file is its own make target, so a plain `make bats-unit-tests` stopped scheduling files at the first red one and never ran the rest, while the output looked like a finished suite. CI passes -k and was not affected; a local run was. The target now runs the files in a --keep-going sub-make, which still exits non-zero when any file fails and shares the caller's job slots and output sync.
