Stopping app does not kill port

[chasefleming]

Describe the bug Stopping Kitty Items does not kill port 3001. Cannot run another application on that port after ctrl c.

To Reproduce

• Run Kitty Items
• Hit control c
• Try running another app on port 3001

by design I guess, it is running via pm as service. npm run stop should stop background services.
