mattpocock/ai-hero-cli ? reverse-engineered prompt

Build me a TypeScript command line tool called AI Hero CLI for working with AI Hero course exercises.

I want it to let a student pick an exercise from the current project, run the exercise entry file, and then keep them moving through the course without having to hunt around folders. It should support running a specific lesson number or opening an interactive picker, and while an exercise is running it should accept simple keyboard shortcuts for next, previous, choose another exercise, help, and quit.

Please make it automatically look for exercises in the expected numbered folder structure, show any instructions from a readme file if there is one, and load environment variables from a local env file so exercises can use API keys or other config. It should also work from a custom root folder and a custom env file path, and have a simple mode for cases where the fancy interactive behavior might not work well.

If you need to check current docs for any tool choices, go ahead and look them up online.
