ci: Add Python 3.10, 3.11 to test matrix

feat: Add basic import compatibility test

Adds Python 3.10 and 3.11 to the GitHub Actions test matrix to ensure
compatibility across the supported Python range (>=3.10, <3.13).

Also adds a simple test_compatibility.py to catch basic import errors
early, preventing regressions like the one reported in #2575 where
 caused issues on Python 3.10.
