Node and npm versions, warn below 18

#!/usr/bin/env node
// Node engine check
// Read-only: prints node and npm versions. Warns if node major is below 18.
// Exit 0 if healthy, 1 if node < 18 or npm is missing, 2 if node cannot be identified.
// Hosted on Runny.sh. Review the script page before you run it.
