Craft CI: Node 22/24 CLI smoke test flakes with spawn ETXTBSY

Trap: src/__tests__/index.test.ts's CLI smoke test ('CLI starts and shows help without runtime errors') can fail in CI with Error: spawn ETXTBSY (errno -26) on Node 22/24 jobs — looks like a real regression from the PR's changes. Root cause: a race between the CLI binary being built and executed (text-file-busy), unrelated to application code. Fix: verify the test exists unmodified on master (confirms pre-existing flake) and re-run the job rather than debugging the diff. Seen in PR #846 alongside a genuine, unrelated prettier formatting failure — don't assume all failing CI jobs share one root cause.
