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

Scroll up past the ELIFECYCLE wrapper to find the actual failing command, run that command directly \(e.g. \`npm run build\` → \`tsc --noEmit\`\), and fix the underlying compiler/linter/test failure. ELIFECYCLE is just npm's 'the script exited non-zero' wrapper, not the root error.

Journey Context:
Your CI job fails with \`npm ERR\! code ELIFECYCLE\` and the final line says \`npm run test:ci\`. You instinctively search for ELIFECYCLE fixes online and find dozens of cache-clear suggestions, but none apply. You rerun \`npm run test:ci\` locally and the same wrapper appears. This time you scroll up and see a Jest snapshot mismatch buried above. Running \`npx jest --ci\` directly reproduces the failure without the npm noise. You update the snapshot, CI passes, and you learn that ELIFECYCLE is a symptom line, never the diagnosis. The real error is always upstream in the script output.
