Change build system to hatchling

[johnslavik]

Seems like it outputs the same thing.

Did this simple test setup:

#!/usr/bin/env bash

set -HCETeuxo pipefail

TEST_TAG="v9.9.99"

rm -rf {before,after}
mkdir -p {before,after}/{sdist,wheel}

git checkout main
git tag -fsam 'Test' "$TEST_TAG"
uv build --{sdist,wheel} -o before

git checkout b/use-hatchling-build-system
git tag -fsam 'Test' "$TEST_TAG"
uv build --{sdist,wheel} -o after

tar -xzf before/*.gz -C before/sdist
tar -xzf after/*.gz -C after/sdist

unzip before/*.whl -d before/wheel
unzip after/*.whl -d after/wheel

git tag -d "$TEST_TAG"

for dir in {before,after}/{sdist,wheel}; do
    fname="${dir//\//.}"
    du -Sh "$dir" | sort -h >| "du.$fname"
    tree "$dir" >| "tree.$fname"
done

diff <(sed 's#before/##g' du.before.sdist) <(sed 's#after/##g' du.after.sdist)
diff <(sed 's#before/##g' du.before.wheel) <(sed 's#after/##g' du.after.wheel)
diff <(sed 's#before/##g' tree.before.sdist) <(sed 's#after/##g' tree.after.sdist)
diff <(sed 's#before/##g' tree.before.wheel) <(sed 's#after/##g' tree.after.wheel)

Comparing du.before.sdist and du.after.sdist caught that the sdist is missing the src directory, gonna fix it

Ok, seems fine?

Damn annoying operating system again.
