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.
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.
Replace polygon boolean clipping with direct entity splitting using
bounding box filtering and exact intersection math. Eliminates Clipper2
precision drift that caused contour gaps (0.0035") breaking area
calculation and ShapeBuilder chaining.
Also fixes SpikeGrooveSplit: spike depth is now grooveDepth + weldGap
(spike protrudes past groove), both V-shapes use same angle formula,
and weldGap no longer double-subtracted from tip depth.
SplitDrawingForm: fix parameter mapping (GrooveDepth direct from nud,
not inflated), remove redundant Spike Depth display, add feature
contour preview and trimmed split lines at feature positions.

- Replace raw Panel with EntityView (via SplitPreview subclass) for proper
zoom-to-point, middle-button pan, and double-buffered rendering
- Add draggable handles for tab/spike positions along split lines; positions
flow through to WeldGapTabSplit and SpikeGrooveSplit via SplitLine.FeaturePositions
- Fix OK/Cancel buttons hidden off-screen by putting them in a bottom-docked panel
- Fix DrawControl not invalidating on resize
- Swap plate Width/Length label order, default edge spacing to 0.5
- Rename tab labels: Tab Width→Tab Length, Tab Height→Weld Gap, default count 2
- Spike depth now calculated (read-only), groove depth means positioning depth
beyond spike tip (default 0.125), converted to total depth internally
- Set entity layers visible so EntityView renders them

- SpikeParameters: added GrooveDepth (how deep groove cuts into
receiving part) and SpikeWeldGap (gap between spike tip and groove)
- SpikeGrooveSplit: groove uses its own depth (wider/deeper than spike),
spike tip stops short by weld gap amount
- UI: added Groove Depth and Weld Gap fields to spike parameters panel
- Changed default pair count to 2 (one near each end)
