    If a directory named node_modules exists, then run npm run start. Else run npm ci and then npm run start.

    The objective is to only run npm ci if node_modules doesn’t exist.

    Basically -d tests for directory existence and runs npm run start, otherwise it will run npm ci && npm run start
