refactor(posts): move post-processor projects under Posts/

Group the Cincinnati and GravographIS plugin projects in a Posts/
folder so new machine posts have one home. Project names, namespaces,
and the runtime Posts/ deploy target are unchanged; only relative
paths in the solution and project references move.

 `OpenNest.WinForms.Tests` contains the desktop-assembly-dependent `CadBendNoteTests` (`CadText`) and `CuttingParametersSerializerTests` (`CuttingParametersSerializer`). It targets `net8.0-windows`, references `OpenNest`, and requires a Windows runner: `dotnet test OpenNest.WinForms.Tests/OpenNest.WinForms.Tests.csproj`. Keep future desktop-dependent tests here rather than in `OpenNest.Tests`. Linux cross-compilation uses `dotnet build OpenNest.WinForms.Tests/OpenNest.WinForms.Tests.csproj -p:EnableWindowsTargeting=true`; cross-compilation is not Windows runtime verification.
