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.

Compare cutout proposals, frame angles and bundles by insert outline area,
and add bounded largest-first packer candidates so big parts get the first
move in an empty hole. On the real job the four frames go from 54-70% to
77-81% filled.

Private copies of tolerant box containment, box union, vector rotation and
the cutout proposals' coordinate-range check now use one helper each:
BoundingBox.IsWithin and BoundingBox.Union, Vector.Rotate, and
CutoutCoordinates.WithinRange. Tests pin the helpers bit-for-bit against
frozen copies of the removed bodies. No behavior change.

Profiling the cutout pre-pass on real round-part jobs put ~97% of its time in
the frame-wall NestLayoutCheck.Clears inside CutoutCirclePacker.Fill. Ear-clipped
round frames make every perimeter/insert triangle pair overlap, so a clear pair
runs hole subtraction for every pair. The same question repeats for every frame
angle and repeated frame instance, because Automatic inserts get identical
frame-local poses.
- CutoutMemo, one per Prepare, replays geometry reads, circle items and Clears
answers. Keys hold geometry by reference, pose bit patterns, argument order
and spacing. It is threaded through CutoutCirclePacker.Fill and the router's
round-only path.
- TriangulatedRegion.SubtractAllHoles measures each piece's bounds once, skips
holes and hole triangles that no piece reaches, and ping-pongs the remainder
between scratch buffers instead of copying it into pooled ones. Clip
arithmetic and order are unchanged.
Bundles are byte-identical on 14 real and 10 synthetic ring jobs. Pre-pass time
over the real set drops from 99.6 s to 10.1 s (N0414-02 35.8 s -> 0.6 s).

Add CutoutCirclePacker, a circle-in-circle proposal for the cutout
router. When a cutout is one circle and every insert fills at least 0.8
of its enclosing circle, it packs the inserts largest first at centers
tangent to the wall or placed discs, trying a center-out pass (a single
insert sits concentric) and a wall-first pass (optimal counts for up to
nine equal discs). Every pose passes NestLayoutCheck.
The router runs it first and skips the lattice and NFP searches when it
places all demand; otherwise the higher count wins and existing
proposals keep ties. On synthetic disc jobs the prepass drops from
minutes to seconds and places as many or more inserts.
