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

Look at the lines immediately above the ELIFECYCLE message for the real command failure \(e.g. \`tsc\`, \`eslint\`, \`jest\`\). Fix that underlying error; the ELIFECYCLE wrapper is only reporting the non-zero exit code. If the script itself is wrong, inspect \`package.json\` scripts and run the command directly \(e.g. \`./node\_modules/.bin/eslint .\`\) to see the actual output without npm’s wrapper.

Journey Context:
A developer runs \`npm test\` and sees \`npm ERR\! code ELIFECYCLE\`. They initially think npm itself is broken and delete \`node\_modules\`. The error persists. They learn that npm wraps lifecycle scripts and prints ELIFECYCLE whenever the script exits non-zero. They scroll up and find the real failure: Jest cannot parse a file, or TypeScript has a type error. They fix the actual test or type error, rerun \`npm test\`, and ELIFECYCLE disappears because the wrapped command now exits 0.
