Summary

This pull request removes the legacy setup.cfg so package metadata lives only in pyproject.toml, same as slackapi/bolt-python#1616.

• pip show slack-sdk output is unchanged (Home-page, Author, Author-email), so Configuring with pyproject.toml #1436 still holds.
• Only caveat: pip older than 24.1 shows an empty Home-page.

Testing

1. ./scripts/build_pypi_package.sh
2. Install dist/*.whl in a fresh venv and confirm pip show slack-sdk matches the current release

Tested locally following the steps in the description:

1. ./scripts/build_pypi_package.sh builds the sdist + wheel and twine check passes on both.
2. Installed the wheel in a fresh venv (pip 26.3): pip show slack-sdk matches the current 3.46.0 release from PyPI exactly (Home-page, Author, Author-email, License).

Also confirmed the pip < 24.1 caveat (pip 24.0 shows an empty Home-page, Author fields still fine), and nothing else in the repo references setup.cfg. LGTM!

[srtaalej]

Nice, splitting name and email into separate entries is what keeps Author: and Author-email: as two fields. A combined { name, email } entry would emit only Author-email: "Slack Technologies, LLC" <opensource@slack.com> and change the pip show output.

Confirmed this shows up as Project-URL: Homepage, ... in METADATA instead of the old Home-page: header. pip 24.1+ maps it back to Home-page in pip show, while pip 24.0 shows it empty, matching the caveat in the description. Seems fine to me.

[srtaalej]

Not for this PR: setuptools warns that the table form of license is deprecated (and so is the license classifier). Moving to license = "MIT" needs setuptools>=77, which doesn't work with our Python 3.7 support, so maybe that's a follow-up once we drop older Pythons.
