Free-threaded Python builds (e.g.
3.13t) can expose issues invisible on the standard interpreter, even without multithreaded tests. The CI matrix had no coverage for them.Changes
3.13t— added to the mainpythonmatrix, so it runs across all three platforms (ubuntu, macOS, Windows), consistent with how stable3.13is tested3.14t— added as anincludeentry scoped toubuntu-latest, consistent with how the pre-release3.14is handled3.15tintentionally excluded until 3.15 is stable
