Let's go ahead and do SPEC0 + 1yr for the scipy bits.

I think I'll need to make a nibabel release for numpy 2/Python 3.13 support.

@Remi-Gau We can split out the Python 3.8 drop / minimum dependencies bump from the 3.13 support. Then the 3.13 PR can just be periodically bumped as dependencies add support.

OK will extract the 3.13 part in a separate PR
