NestDxfJob imports a DXF folder plus a quantity workbook, runs a
registered whole-job engine, and only publishes a nest that passes
quantity, bounds, overlap/spacing, and cut-only checks both before and
after save/reload. Writes import and validation reports; partial or
invalid results exit nonzero. Standalone project (not in the solution);
documented in the README.
Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
PolygonHelper.ExtractPerimeterPolygon always used OffsetSide.Right
assuming CCW winding, but DXF imports can produce CW winding. This
caused the spacing polygon to shrink inward instead of expanding
outward, making parts overlap during nesting.
Now detects winding direction via polygon signed area and selects
the correct OffsetSide accordingly.
Also adds save_nest MCP tool and a BOM-to-nest builder utility
(tools/NestBuilder) for batch-creating nest files from Excel BOMs.
