Add missing py.typed in module directory

[wdlowry]

Pyright was complaining about a missing stub file. After digging in a little, I noticed that py.typed is missing the module directory. This PR adds it.

Test:

❯ python -m build
...
Successfully built mailgun-1.6.0.post1.dev1.tar.gz and mailgun-1.6.0.post1.dev1-py3-none-any.whl
❯ unzip -l dist/mailgun-1.6.0.post1.dev1-py3-none-any.whl | grep py.typed
        0  02-12-2026 13:23   mailgun/py.typed

@wdlowry The file py.typed is packaged in the project folder https://github.com/mailgun/mailgun-python/blob/247d2f4f3587b74430404a4c6a3a19b2e106704d/pyproject.toml#L117C14-L117C19. The Source Distribution on PyPI has it https://pypi.org/project/mailgun/1.6.0/#files (or see here https://inspector.pypi.io/project/mailgun/1.6.0/packages/a6/36/90051ee5ba055ae35f2c6ab8a37429dcaaafef0dcdab6aeb426e03ce1a3c/mailgun-1.6.0.tar.gz/)

python -m build
tar -tf  dist/mailgun-1.6.0.tar.gz | grep py.typed
mailgun-1.6.0/py.typed

But you're right, the wheel file doesn't include it https://inspector.pypi.io/project/mailgun/1.6.0/packages/98/ac/6dfdd71f94d9cc82be5c0925730722b421c123b4471a2706d88e3592480b/mailgun-1.6.0-py3-none-any.whl/

Is it critical for your workflow to have it in the wheel file, or can you use it from the Source Distribution (tar.gz)?

@wdlowry PEP 561 confirms your suggestion: py.typed must physically reside in the mailgun/ package directory.

Will fix it in the next release.

Thank you!

Will fix it in the next release.

Thank you for getting this!
