Support Python 3.14, and test against PyPy 3.10+ (#1104)

This introduces the following changes:

* tox is configured to test CPython 3.14, PyPy 3.10, and PyPy 3.11.
* GitHub CI is configured to install those same interpreter versions.
* The PyPI trove classifiers are updated.
* The `tests` extra is updated to resolve Python 3.14 failures
  caused by old pytest code that used now-removed `ast` symbols.
  (The coverage version is updated as well.)
