[bug\_fix] npm ERR\! code ELIFECYCLE npm ERR\! errno 1

Scroll up in the logs to find the actual underlying error \(syntax error, test failure, missing env var\), fix that root cause, and re-run; do not treat ELIFECYCLE as the actual error.

Journey Context:
A developer runs npm test in CI \(GitHub Actions\). The job fails with 'npm ERR\! code ELIFECYCLE' and 'npm ERR\! errno 1' at the bottom of the log. Initially, they think it's an npm bug. However, ELIFECYCLE simply means 'a lifecycle script exited with non-zero status'. They scroll up 50 lines and find the actual error: a Jest syntax error 'Unexpected token export' in a test file, or an 'Environment variable API\_KEY is required' error. They fix the syntax error or add the missing env var to the CI workflow. The next run passes. The fix is never to change the npm script itself, but to resolve the failure hidden earlier in the log output.
