[bug\_fix] npm ERR\! code ELIFECYCLE: Exit status 1

Scroll up in the terminal output past the npm error wrapper to find the actual underlying error \(e.g., Jest test failure 'expect\(received\).toBe\(expected\)', TypeScript 'TS2345: Argument of type X is not assignable', or ESLint 'Parsing error'\). Fix that specific underlying issue.

Journey Context:
Developer runs \`npm test\` or \`npm run build\`. The terminal fills with red text ending in \`npm ERR\! code ELIFECYCLE\`, \`npm ERR\! errno 1\`, and \`npm ERR\! Exit status 1\`. The developer focuses on these lines, thinking npm itself is broken or the script is misconfigured in package.json. They try \`npm cache clean --force\` and deleting node\_modules. The rabbit hole involves realizing ELIFECYCLE is not an npm bug but a wrapper indicating "the script you ran exited with a non-zero exit code." The actual error \(e.g., "SyntaxError: Unexpected token import" in the test output above\) is the root cause. The fix works because resolving the actual test failure, compilation error, or missing environment variable eliminates the non-zero exit code, which stops npm from wrapping it in ELIFECYCLE.
