npm EACCES on global install

npm ERR! code EACCES
npm ERR! syscall access
npm ERR! path /usr/local/lib/node_modules

Fix:

Don't use sudo npm. Move npm to a user-owned prefix:

mkdir ~/.npm-global
npm config set prefix ~/.npm-global
export PATH=~/.npm-global/bin:$PATH  # add to ~/.zshrc or ~/.bashrc
npm install -g openclaw
