What's Wrong?

Cowork/update broken on Windows — matches GitHub #70733 (rootfs.vhdx never downloads) on one machine, and #36642 (EXDEV rename failure) on a second machine. A third install/update attempt on the first machine failed with the same AddPackage HRESULT 0x80073CF6, now blocking all future updates as well
