ensure sdists are installable

[jameslamb]

The v0.11.1 sdists were not installable. #359 tried to fix that but... the v0.11.2 sdists aren't installable either (https://github.com/conda-forge/pydistcheck-feedstock/pull/20/files#r2696726737).

All of these are my failed attempts to switch the build backend to hatchling 😭

This PR tries to fix it for good, and adds even stricter testing.

• uses the sdists in some of the unit test CI jobs
• updates path re-mapping so that wheels built from the sdist are installable

[jameslamb]

I think this was the problem. The sdist didn't have src/ paths, so this didn't exist when building a wheel from the sdist.

Might be able to get away without any configuration in [tool.hatch.build.targets.wheel], based on https://hatch.pypa.io/latest/plugins/builder/wheel/#default-file-selection

Planning to immediately release this as v0.11.3

[jameslamb]

Ok I think this is working? Let's try it again 😅

[jameslamb]

I think this worked! The conda-forge builds (which build from the sdist) passed: conda-forge/pydistcheck-feedstock#22

And I tried installing the newly-published sdist in a totally clean image and saw it work.
