Major Python version jump skips untested Python 3.14

High Severity

The upgrade from python:3.10.4 to python:3.14.3 jumps 4 minor versions to a Python version that is not included in the project's official classifiers in pyproject.toml. The classifiers list Python 3.9 through 3.13 but explicitly omit Python 3.14, indicating this version has not been tested by the maintainers. This significant version jump could introduce runtime compatibility issues from deprecated API removals or behavior changes between Python 3.10 and 3.14.
