Subject: [PATCH] Update Python versions to 3.12-3.14

CI and the project configuration currently target Python 3.9, which is now end-of-life.

This commit updates the project configuration to use version 3.10 and higher, and does CI testing on versions 3.10-3.14. It does simplified tests on Ubuntu for all supported Python versions (3.10-3.14), plus detailed CI on all supported platforms (Ubuntu, macOS, Windows) on 3.14.
