Fix post-merge tests

[bryanwweber]

Changes proposed in this pull request

• Set up the SpecifierSets for version comparisons to allow pre-release versions of packages. This shouldn't change any behavior for stable versions.
• hdf variables no longer need to be specified to SCons CLI, they're handled by SConstruct since Configure libhdf5_serial if it's available #1723
• Install pre-release wheels from the anaconda index for NumPy, SciPy, Pandas, and Cython. This means we don't have to build them ourselves 🎉
• If the Python package is built for a newer version of Python than we support, ignore pip's error about unsupported Python because the user is warned by SCons anyways
• Add support for Python 3.13 to the extensions

I've been wondering if we should update the default to build the Python package unless it is explicitly disabled, so that missing a Python dependency results in a build failure unless you set python_package=n.

[bryanwweber]

I'm for it! Do you want to make an enhancements issue so we can at least try to document some tradeoffs?

As of yesterday, Pandas pre-release wheels were available for Python 3.13: https://github.com/Cantera/cantera/actions/runs/10207129578/job/28266033217 They are no longer available right now 😞

[bryanwweber]

I also don't think I did anything that would start causing the sample tests to fail. It does look like the artifact uploaded of libcantera_shared is not correct, it's only a few hundred bytes as opposed to the kB that are uploaded on main. 🆘

[speth]

It's uploading the symlink, not the actual file the symlink points to. Seems to be an unexpected change introduced in the latest version of upload-artifact, as reported in actions/upload-artifact#589.

[bryanwweber]

That was my guess, that it was uploading the symlink. Glad to know it's not just us. I'll pin to 4.3.4 for now.

[bryanwweber]

Based on pandas-dev/pandas#59372, it looks like wheels get removed after some time in the nightly index, probably to avoid overloading Anaconda's willingness to provide storage 😬 And as it happens, Pandas wheels haven't been uploading for a while, due to test failures on their part. So I'm fine with accepting those jobs failing.

Thanks, @bryanwweber. This all looks fine to me.
