fzrilsh/bercocok-tanam ? reverse-engineered prompt

Build me a Node.js CLI tool that can take a list of test accounts from a file, run browser based automation on them in parallel, and save a clear report of what worked and what failed.

I want it to be easy to configure from a .env file, with settings for how many workers to run, headless mode, timeouts, delays, and output file locations. It should support a few different automation flows, let me run one or all of them together, and keep track of progress so the same account does not get processed twice. If a run fails, log the account and the error in a separate file with timestamps.

Make the interface simple and friendly from the terminal, with helpful prompts if the account list changes. Use current docs online if you need to. Also include a clean README, sample env file, and sensible defaults so I can get it running quickly on Node 16 or newer.
