Grows part-to-part spacing of a selected group with the work area and
non-selected parts as hard boundaries. Doubling + bisection search over
the target spacing; Gauss-Seidel straight-line relaxation with anchor
mover policy (later-index selected part moves, first selection never).
Overlapping input is separated along penetration MTVs instead of being
rejected. Cancel/failure never mutates part positions. Clearance gains
BoundaryDistance for ring-pair gaps (part-in-cutout legality).
ShrinkAxis.Length must shrink the Y extent and ShrinkAxis.Width the X
extent to agree with MeasureDimension/TrimToCount; Box's constructor
takes the X extent first. The estimate previously shrank the wrong
dimension and returned a mis-ordered box. Add a parameterized regression
test over both axes and both translated-remnant orientations.
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.
SortStrips measured the gap between only the first two strips in original
placement order and replayed that single value between every strip after
reordering by height/width. Real (non-uniform) geometry produces varying
inter-strip gaps, so resequencing could expand the total footprint beyond
the plate's already-fitted work area, crashing StripPlateNester with
"Candidate placement falls outside the usable stock area." Using the
actual required spacing guarantees the resequenced span never exceeds
the original, since real gaps are always >= spacing.
