[clad] Test clad master

Adding the clean build tag - incremental builds don't rebuild Clad actually, which is why we only only se the failures on macOS so far. But I see them also locally. I'll open a reproducer on GitHub in a sec

Looks like things now fail and I bet is the new clad master... Can you help reducing or maybe we have not landed all fixes we were supposed to..

Thanks for this! By the way, before releasing a new Clad version, it would be nice to wait until this PR is merged so we can easily test Clad master with that new neural network flow:

• [tmva][sofie] Restructure emitted code to be differentiable with Clad #18332

Ok. Then I am waiting for your green light here once we have it I can release.

The RooFit and SOFIE gradient applications work. But it would be quite nice if the next Clad release would support also some basic RooFit Hessian examples. This is right now blocked by vgvassilev/clad#1804, which is representative for all combined fits because they use this nested function pattern.

But we have not promised the Hessians for CHEP 2026. This is just in the general 2026 plan of work. So up to you @vgvassilev if you want to release now, or if you want to do this only after fixing the Hessians. I'm fine with both, as long as there will be another Clad release planned at the end of the next quarter that we could pick up for working Hessians in ROOT 6.42!
