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.
Curved leads turned with the contour winding, which is backwards on outside
perimeters: arc lead-ins arrived against the cut, and Line + Arc / arc
lead-outs went the long way round on one winding. LeadTurn now gives the
arc's turn direction for emission, the pierce-zone check and the preview,
and the arc geometry mirrors with it.
At convex outside corners, curved lead-ins use the first-cut edge's normal
and arc lead-outs the last-cut edge's, whichever edge was picked.
ArcLeadIn gains SweepAngle (degrees, (0, 180], default 180) in the cutting
panel, settings, nest files and cut pins; older files read as 180.

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.
The offset direction (start→pierce) is reversed from the approach
direction (pierce→start), so the old formula produced 180°−angle
instead of the requested angle. Invisible at the 90° default but
caused 45° to render as 135°.

Scales down lead-ins that would place the pierce point too close to the
opposite wall of small holes. Uses quadratic solve to find the maximum
safe distance inside a clearance-reduced radius. Adds Scale() method to
all LeadIn types and applies clamping in both the strategy and the
interactive preview.

Restructure the cutting parameters dialog with separate Lead-In and
Lead-Out GroupBoxes per tab, exposing editable length/angle/radius
fields for lead-outs (previously hardcoded). Add Tabs section with
enable checkbox and width control. Also fix lead-in/lead-out angle
calculations and convert cutting strategy output to incremental mode.

Adds LayerType.Leadin to all LinearMove and ArcMove instances produced
by LineLeadIn, ArcLeadIn, LineArcLeadIn, CleanHoleLeadIn, and
LineLineLeadIn Generate() methods, plus tests covering all subclasses.
