vulkansdk-macos-1.3.261.1.dmg left around on disk

Describe the bug

core setup

this runs perfectly fine, but leaves the vulkansdk-macos-1.3.261.1.dmg on disk

just need to remember to delete if the install succeeds.

I thought that maybe its left around because then you would check for it and then not curl it again, but thats not the case.

The other fix is for the core system to have its own dedicated file cache but thats maybe not really needed.

Yep, I will try to have it delete it. I thought I might have tried to delete it before and there was some issue with ejecting it properly, but this should be doable.

This is no longer relevant since we switched over to WebGPU (#507).
