Windows CI was timing out at 30 minutes due to fundamentally slow I/O
(NTFS, Defender scans, slow Git). RAM disk experiments didn't help enough.
Replace two parallel full test jobs with single smoke test job that:
- Builds bd.exe
- Runs version check
- Tests init, create, list, show, update, close
Should complete in <2 minutes vs 30+ minute timeouts.
