[bug\_fix] ELIFECYCLE exit status 1 \(npm script failure wrapper\)

Scroll up in the terminal output past the ELIFECYCLE error to find the actual underlying error \(syntax error, test failure, build error\). The root cause is ELIFECYCLE is just npm's way of reporting that a lifecycle script returned a non-zero exit code, not the actual error itself.

Journey Context:
You run npm run build or npm test and see 'npm ERR\! code ELIFECYCLE' and 'npm ERR\! errno 1'. You search for 'ELIFECYCLE error' and find stack overflow posts suggesting you delete node\_modules and package-lock.json, clear npm cache, or reinstall Node.js. You try all of these but the error persists. You eventually realize that ELIFECYCLE is just the exit code wrapper npm uses when a script fails. You scroll up in your terminal output above the npm ERR\! lines and find the actual error: a TypeScript compilation error, a Jest test failure, or an ESLint syntax error. The fix is to address that specific underlying error, not the ELIFECYCLE wrapper.
