Fully autonomous long-horizon engineering loop: Pitch an idea → rough plan → run the entire project automatically (decision points pick the best option automatically), and only call the user in for verification at the end. Cross-tool orchestration of gstack (review) / OpenSpec (spec) / GSD (build) / Superpowers (guard) / CCG
