martyr-deepin/deepin-installer-reborn — reverse-engineered prompt

Build me a graphical Deepin Linux system installer that can run in the live install environment and guide someone through installing the distro onto their computer.

I want it to feel like a simple release ready installer, not a developer demo. It should help the user choose where to install, prepare disks and partitions, format common Linux and Windows friendly file systems like ext4, FAT, NTFS, btrfs, XFS and similar, support LVM where needed, show clear warnings before erasing anything, then show install progress and a clear finish screen.

Please make it in C++ with Qt 5 or newer, and keep it suitable for a minimal installer session. Don’t depend on DBus, a window manager, drag and drop, or clipboard actions. Also include the basic test runner and an OEM tool entry point like the project expects.

Look up current docs online if you need to, but keep the app focused and practical.
