Subject: [PATCH 1/2] fix: include tests/ (and tox.ini) in the flit sdist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #261 — flit_core sdists omitted the test suite while shipping
tox.ini, so distro packagers could not run the project's tests from the
PyPI source tarball. Explicitly include tests/ and tox.ini; keep docs/
and benchmarking/ excluded.
