Support for npm/yarn scripts

[cmwd]

This transform works only if an app is executed directly from the node. Because npm/yarn adds own non-json logs to the output it throws SyntaxError: Unexpected end of JSON input.

Maybe we could simply detect if the log comes from pino and if not just ignore it?

Thanks,
Piotr

Yes. It should also validate the JSON parsing like https://github.com/pinojs/pino-filter/blob/5445b1621391551a05b53a89379b49ed80de4e1c/index.js#L116-L120
