Create the WhiteMagic net8.0-windows class library and the WhiteMagicTest
xUnit project, grouped in WhiteMagic.slnx (SDK 10 default format). Library
enables nullable, unsafe blocks, x86/x64 platforms, warnings-as-errors.
Empty solution builds clean (0 errors, 0 warnings).
Add AGENTS.md (ASD-STE100) defining the build/test commands, the test-first
rule, and the one-feature-one-branch workflow with review before merge to
master.
Mark project-setup tasks 1.1-1.3, 1.5 done; 1.4 (Native P/Invoke surface)
is the first feature branch.
