Every nesting-geometry consumer filtered only rapids, so scribe/etch
moves counted as part material. An etch tick that ends a hair outside
the outline (PEP bend ticks start on the notch edge) made the part
"open geometry leaving the material region": the job validator threw
and every built-in engine plus Gpt6Astra crashed on real PEP jobs
(PT75, drawing 4980 A01 PT77). Marks are only on the surface, so they
should never affect placement, collision, area, or validation.
- SpecialLayers.IsMaterial excludes Rapid and Scribe; used by drawing
area, canonical angle, part collision, PartGeometry, plate perimeter,
best-fit/pair evaluation, rotation analysis, GPU evaluators, and both
validators. Timing, display, splitting and posts still see marks.
- ConvertGeometry also maps the saved SCRIBE layer name to Scribe, so
programs rebuilt from stored entities keep their marks.
- NestReader repairs older files (e.g. PepNestExport output) whose
programs saved etch as cut moves while source entities kept SCRIBE.

Part.Rotation is cumulative, so rebinding canonical parts with
CreateAtOrigin(original, p.Rotation) double-counted the drawing's own
rotation, and FromCanonical rotated each part about its Location, which
moved it off its slot and out of the work area. Add
CanonicalFrame.RebindToOriginal (rotation = part - original program
rotation, footprint aligned to the canonical part) and use it in the
three places that duplicated the old logic.
The MBR only fixes the frame modulo 90 degrees and nest results are not
90-degree symmetric (an L gave 56/43/42/42 parts by orientation).
CanonicalAngle.Compute now picks one of the four orientations from the
centroid offset; symmetric shapes keep the MBR orientation.
Fixes the three NestInvarianceTests.

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.
