JCVERSA/bot ? reverse-engineered prompt

Build me a WhatsApp multi device bot called Nebula Bot that uses a session string or QR login, and can be run from Node 18 or newer.

I want it to feel lightweight and easy to customize, with commands split into separate files so I can add or edit features without digging through the core code. The bot should let me change things like the prefix, bot name, bot image, and channel or newsletter details through simple commands or config settings. Please include the basic owner tools too, like restart and update from zip, plus clean session handling and sensible media handling so it stays stable and does not waste memory.

Set it up so I can run it locally with one main start file, and make sure there is a clear config file and example environment file for session ID and other settings. If you need anything current from the Baileys docs, look it up online first.
