Subject: [PATCH] ci: run make check on ubuntu / windows (MSYS2 UCRT64) / macos
 (#140)

The repo's own dependency-free gate, on the three claimed platforms, for
every PR and push to main/dev. The windows job is the one that would have
caught #68/#137 pre-merge. No CUDA, no Metal, no model downloads in v1.
