Build issues on NixOS 24.11 Stable

[addy419]

There's a build error while building cosmic-comp on NixOS 24.11, not sure if this warning is the reason for this:

warning: this function depends on never type fallback being `()`

That's odd, I haven't had any issues building for 24.11 in my own CI

@drakon64 My bad, I was running out of memory (according to htop). Using --cores 1 and -j 1, I was able to bring the memory usage down to 50GB and got it compiled successfully.
