Geometry, nesting and import code now call PortableMath instead of
System.Math for Sin, Cos, Tan, Atan, Atan2, Asin and Acos (Core, Engine,
IO, Data; 269 calls in 64 files). A test fails if those projects call the
runtime's trig again.
With the runtime's trig, Windows and Linux disagreed in the last bit at
non-quarter angles and the same job could nest differently: the
learned-angle nests (a cross fixture) placed 23 parts in Strip on Windows
and 28 on Linux. Now every Engine.Tests pin gives the same layout on both
(3600 passing on Linux and on DesktopPC), Linux layouts are unchanged, and
the learned-angle rows are re-pinned to the shared layouts, which pass the
overlap and work-area checks, and run on every platform again.
Fixes Project Memory 518f3b58.
The Drawing Library Grid check found seven drawings with 1,000-1,700
holes (90-6138-26/27, Reeves bakery vent pans, 4938 A15) that took
0.5-3.6 s to preview, all of it in the part label point.
- PolyLabel skips a hole's containment test outside its bounds and its
edge distances when its bounds are farther than the nearest edge so
far. Both skips leave the result exactly as before; label points on
all seven drawings are unchanged and the search is 4-35x faster.
- ShapeBuilder.GetShapes rescanned every remaining entity at each
chaining step. An endpoint grid now finds the candidates, tested in
list order with the same checks, so chosen entities, reversals and
shapes are identical (compared against the old loop on the library
drawings and 300 random entity soups). 90-6138: 700 ms -> 40 ms.
- The label builds its shapes once: ShapeProfile.FromShapes reuses the
ones it already chained instead of chaining them again.
Previews of all seven now take 57-166 ms.

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.
