Use nodemon for automatic server reloading in development

[tsibley]

Handy when working on server-side code.

(and maybe you can manage to convince your brain to read "nodemon" as "Node mon(itor)" and not "no demon"…)

Testing

• [x] Works locally
• [x] Checks pass

I've always read it as "nodémon" à la "Pokémon" :)

Amazing. I love it. :upside_down_face:
