Nekros-dsc/Doggy-Bot — reverse-engineered prompt

Build me a Discord bot called Doggy Bot in JavaScript. I want it set up cleanly so it can load normal prefix commands, slash commands, and event listeners from separate folders, with a main entry file and simple config values for things like the bot token and prefix.

Please make it feel like a real usable starter bot, not just a bare skeleton. Add a few basic commands so I can test that everything works, like ping, help, and a simple fun or utility command, and make sure slash commands are registered properly. I also want lightweight local data storage so the bot can save small bits of info without needing an external database.

It should handle errors nicely, log when it starts up, and be easy to extend with more commands later. If anything is missing, use sensible defaults and keep the code organized. You can look up current Discord bot docs if needed.
