Linzh1998/MegaMedusa ? reverse-engineered prompt

Build me a simple Node.js website load testing tool that can send a chosen amount of traffic to a site I own or have permission to test, then show me basic stats like how long it ran, requests per second, and whether requests were succeeding or failing.

I want it to support using a proxy list for testing from different locations, and it should be easy to run from the command line with a target URL, test duration, traffic level, and number of workers. Please make it work on common desktop systems and keep the setup straightforward with a small installer or setup script.

If you need current docs or examples for any libraries, look them up online. Keep it safe, legal, and focused on legitimate stress testing and debugging rather than anything that tries to bypass protections or attack real services.
