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

Scroll up in the terminal output to find the actual error thrown by the script \(syntax error, test failure, missing env var\), not the ELIFECYCLE wrapper

Journey Context:
Developer runs npm test or npm run build and sees ELIFECYCLE error with errno 1. They interpret this as an npm internal failure and run npm cache clean --force, delete node\_modules, and reinstall, but the error persists. After frustration, they carefully scroll up past the npm ERR\! lines and discover the actual error: a Jest snapshot mismatch, or a TypeScript compilation error "Cannot find module './types'", or an eslint parsing error. The ELIFECYCLE error is merely npm's way of saying "the script you ran exited with code 1". The fix is always to fix the underlying tool's error \(the test failure or build syntax\), not to treat ELIFECYCLE as the root cause.
