Jest without a TTY prints "FAIL jt/add.test.js" with one space; the parser
matched two, so a real jest load failure read ERROR, not UNVIABLE. The old
`^ +● ` denylist also named process.exit's "● process.exit called with "1""
as a killing test (CAUGHT). Names now need a FAIL file header above them; a
crash with no named failing test is ERROR. The "no test counts recognised"
line names jest. The synthetic jest logs and mock are replaced by real jest
29.7.0 output captured on Yggdrasil from tools/fixtures/mutation-probe/jsr
(green, wrong, load, exit runs in logs/jest-real.log).
