[bug\_fix] npm ERR\! code ELIFECYCLE

Ignore the npm wrapper message and read the actual stdout/stderr lines immediately above \`npm ERR\! code ELIFECYCLE\`. The failure is almost always in the script command itself \(a compiler error, a test assertion, a missing file\), not in npm. Fix the underlying command, or if the script is \`npm run build\`, run the raw build command directly \(e.g., \`vite build\` or \`tsc\`\) to remove the npm noise. Only if the script itself succeeds outside npm should you delete \`node\_modules\` and the lockfile and reinstall.

Journey Context:
You run \`npm run build\` and npm dumps \`npm ERR\! code ELIFECYCLE\`, \`npm ERR\! errno 1\`, and \`npm ERR\! [email protected] build: tsc && vite build\`. You initially think npm is broken and reinstall everything, but the reinstall changes nothing. Then you run \`npx tsc --noEmit\` directly and immediately see a real TypeScript error about a missing import. You realize npm was only reporting the exit code of the script it spawned; the actual failure was hidden in the build tool output a few lines earlier. Once the TypeScript error is fixed, the lifecycle script completes.
