// Cold-start budget for spawning the real built binary. Under the coverage
// run's V8 instrumentation + full-suite parallel load the child's cold start
// can exceed a tight 5s budget → status:null (killed) → flaky failure on the
// `npm test` (coverage) variant. 15s absorbs that load; the binary still exits
// near-instantly for --version/--help in the common case.
