Summary

This pull request removes the legacy setup.cfg so package metadata lives only in pyproject.toml.

• setup.cfg was added in Maintain metadata #999 to keep Home-page, Author, and Author-email in pip show after Configuring with pyproject.toml #996.
• authors is now two entries, one name-only and one email-only. PEP 621 maps those to Author and Author-email exactly as before. A single entry with both would render Author-email: "Slack Technologies, LLC" <opensource@slack.com> with an empty Author.
• Homepage is added to [project.urls]. Core metadata has no pyproject.toml field for Home-page, and pip 24.1+ fills Home-page in pip show from this URL.
• Built METADATA diff against main: only Home-page: removed and Project-URL: Homepage added.
• Caveat: pip 24.0 and older (the newest pip on Python 3.7) show an empty Home-page:. Home-page is deprecated core metadata, and PyPI's sidebar already uses Project-URL.

pip show slack-bolt on pip 25.3, before and after:

Name: slack_bolt
Version: 1.30.0
Summary: The Bolt Framework for Python
Home-page: https://github.com/slackapi/bolt-python
Author: Slack Technologies, LLC
Author-email: opensource@slack.com
License: MIT
Requires: slack_sdk

Testing

1. ./scripts/build_pypi_package.sh
2. In a fresh venv: pip install dist/*.whl && pip show slack-bolt, and confirm the output above.
3. Optionally compare unzip -p dist/*.whl '*.dist-info/METADATA' with a build from main.
