Arachnidd/Empyreus-Limited-Sniper ? reverse-engineered prompt

Build me a Roblox limited sniper app that watches for new limiteds, checks price and profit fast, and tries to buy items when they match my settings. I want a simple config file where I can add my Roblox cookie, my Roblox and Discord IDs, webhook links for success, failures, and updates, plus settings like minimum profit, minimum daily volume, percent deal threshold, and an instant buy price.

It should support both catalog sniping and list sniping, and let me turn each one on or off. I also want it to use proxies and run with pm2 so it can stay online in the background. If it helps, include a small item value checker that can run first to estimate item values before the sniper starts. Make it easy to set up, read the config, and give clear console output so I can tell what it is doing and when it finds something. If you need current Roblox API details, look them up online first.
