Installs Node, pnpm and nub via Homebrew, then sets sensible npm defaults and configures .npmrc.

./node/install.sh

nub comes from nubjs/tap, which is not an official tap, so the install trusts the formula first. See the brew readme for how that works.

For Node version management, run node/nvm.sh to install NVM and set up the LTS version as default. This also appends an auto-switch hook to .zshrc that reads .nvmrc files and switches the active Node version when changing directories.
