mame/quine-relay ? reverse-engineered prompt

Build me a quirky demo app that starts as one Ruby script and then spits out a chain of programs across a huge stack of different languages, ending by producing the original Ruby code again.

I want it to feel like a real quine relay, so each step should read the previous output and generate the next language in the chain. Keep the main entry point simple, with clear instructions for running it on Linux and a way to build any bundled helpers from the vendor folder if they are needed.

Please make it possible to run the full chain from the command line, and include a README style set of steps that shows the order to execute each language. If some interpreters are missing, it’s fine to note that I may need to install them first or look up current docs online. The goal is mostly to impress people with the ridiculous language journey, while still being reproducible from the repo.
