I'm getting Node.js version errors. What should I do?

Vibgrate requires Node.js >= 20.0.0. Check your version: node --version. If too old, upgrade using nvm (nvm install 22), Homebrew (brew upgrade node), or download from nodejs.org. If you have multiple Node versions, use nvm or similar to switch: nvm use 22. CI environments should specify node-version: 22 in their setup steps.
