fix(cli): declare node-pty as runtime dep so npx runfusion.ai terminal works on clean install

node-pty was previously only present transitively via the workspace
@fusion/dashboard devDependency, which is stripped at publish time. Fresh
users running `npx runfusion.ai` hit a 503 "PTY module could not be loaded"
when opening the dashboard terminal. Tightened the package-config guard so
this regression is caught next time.
