Drop Python 3.8/3.9 (EOL), add 3.14 and PyPy 3.11 wheel builds

- Bump python_requires to >=3.10 in setup.py
- Add Python 3.14 wheels for all platforms, but skip free-threaded for now until we actually test that they do work
- Enable PyPy 3.11 wheels on all platforms (Linux, macOS, Windows) and remove obsolete PyPy setuptools pin from pyproject.toml
- Remove redundant macOS x86_64-only builds (universal2 covers both
architectures)
