The ubuntu Node 24 smoke job previously gated the Node 22/26 test runs,
delaying them by a full test cycle. Fold the Node 24 (garnet) leg into
the test matrix and gate every test job only on compile-and-lint plus
its platform's pnpr build, so all Node.js versions and all Windows
chunks start in parallel. The trade-off is that a broken build now
surfaces on all test jobs at once instead of costing a single smoke run.
