wg/wrk ? reverse-engineered prompt

Build me a fast command line HTTP benchmarking tool like wrk.

I want to be able to point it at a URL and have it hammer a server with a chosen number of threads, connections, and duration, then print a clean summary of how many requests it handled, how much data came back, requests per second, transfer rate, and latency stats when asked. It should feel like a modern load tester that can generate serious traffic on a single machine, and it should work well with lots of open connections.

Please also support adding custom headers and a timeout option, and make sure the basic usage looks simple, something like running a test against localhost for 30 seconds. If you can, include support for LuaJIT scripting so I can customize request generation and response handling, plus a couple of example scripts. Use the existing README as the guide and look up current docs online if you need to.
