exercism/go — reverse-engineered prompt

Build me a clean, working local version of this Exercism Go track repo. I want to be able to open the concept and practice exercises, see the learner facing files, run the tests, and trust that the reference solutions and generated test cases all line up correctly.

Please make sure the Go setup feels current, the formatting is consistent, and the usual repo checks pass end to end. If there are scripts already meant for testing or linting, wire things up so they work smoothly. Keep the normal Exercism behavior where learner downloads do not include maintainer only files like metadata and example solutions, but those files should still stay useful inside the repo for verification and generation.

If anything is outdated or missing for local development, fix it in the simplest way that fits this project. A short note on how to run the main checks and work on an exercise locally would be helpful too. Look up current Go and Exercism docs online if you need to.
