Probabilities/Chess-Promo-Generator — reverse-engineered prompt

I want a small command line app in JavaScript that recreates the idea of this old Discord x Chess promo generator, but in a safe way since the original method is patched and no longer works.

Make it feel like the old tool, fast, threaded, and able to read optional proxies from a text file, with a simple start flow and clear console output for progress, success, failure, rate limits, and totals. If real promo generation is not possible anymore, turn it into a realistic simulator or checker style demo that shows how the workflow used to behave without relying on broken endpoints or fake claims.

Please keep setup simple so I can just install dependencies, add proxies if I want, and run one main file. If there are missing pieces, look up current docs online and update anything outdated. I mainly want something polished, stable, and easy to run that matches the vibe of the original project without pretending it still works.
