Pull Request Overview
This PR adds support for Python 3.14 beta by updating configuration files and dependency lists, ensuring compatibility with the latest version. Key changes include updating the pytest distributed execution option in the tests documentation, modifying dependency definitions in pyproject.toml to include Python 3.14–specific variants (including a temporary pydantic dependency and retaining pytz for testing), and updating the GitHub workflow to include a Python 3.14 beta version in the testing matrix.

tests/README.rst:45
- [nitpick] Ensure that the use of '--dist=worksteal' is supported by the installed version of pytest-xdist and that any relevant documentation is updated accordingly.
$ pytest -n auto --dist=worksteal
pyproject.toml:116
- [nitpick] Consider clarifying this comment to indicate that pytz is retained solely for backward compatibility in testing, helping users understand its role despite deprecation elsewhere.
# We've deprecated support pytz, but we still need it for testing that it works with the library.
.github/workflows/unit_tests.yml:64
- After removing the manual installation of pytz, please verify that all testing environments receive the correct dependencies so tests relying on pytz pass reliably.
# need to manually install pytz here, because it's no longer in the optional reqs

Also adds pytz to the test dependency group since it was impossible to run the test suite without it.
Tested locally with uv's python 3.14, and with JIT enabled. Also confirmed that test official passes on 3.14 with the changes to annotations.
