ROCm/rocm-systems ? reverse-engineered prompt

Build me a single repo for ROCm Systems that brings together the different GPU tooling projects in one place, with the code organized so each component can still be built and tested on its own. I want it to feel like one clean workspace for development, docs, CI, and integration, especially for the pieces needed around PyTorch. Include the main project folders, shared code, tests, Python helpers, docs, and anything needed for running checks and formatting. Make the setup easy for someone to clone and get started with, and keep the repo ready for ongoing migration from the older individual projects. If you need to look up current ROCm or build docs online to match the latest setup, go ahead. Also make sure the README and project layout clearly explain what this super repo is for and how to work on the different components without getting lost.
