MAINT: Upgrade stubgen-pyx to 0.2.19 (#2653)

* Upgrade stubgen-pyx to 0.2.19

* ci: show diff on pre-commit failure to diagnose Windows stubgen mismatch

Temporary diagnostic to see what content actually differs when the
stubgen-pyx-cuda-core hook reports modified files on Windows CI.

* Fix Windows encoding issue
