Implements the main Nest() method that ties together sorting,
classification, and placement across multiple plates. The method
processes items largest-first, placing medium/small parts into
remnant zones on existing plates before creating new ones. Includes
private helpers: TryPlaceOnExistingPlates, PlaceOnNewPlates,
TryUpgradeOrNewPlate, FindAllRemnants, and CloneItem.

Adds IsScrapRemnant(), FindScrapZones(), and FindViableRemnants() to
MultiPlateNester. A remnant is scrap only when both dimensions fall
below the minimum remnant size threshold (AND logic, not OR).

Introduces PartClass enum and Classify() static method that categorizes
parts as Large (exceeds half work area in either dimension), Medium
(area > 1/9 work area), or Small.

Implements static MultiPlateNester.SortItems with BoundingBoxArea and Size sort orders, covered by two passing xUnit tests.

Consolidated two stateless classes into one unified API: Dxf.Import(),
Dxf.GetGeometry(), Dxf.ExportPlate(), Dxf.ExportProgram(). Export
state moved into a private ExportContext. Removed bool+out pattern
from GetGeometry in favor of returning empty list on failure.

Tries each candidate plate size via the nesting engine, compares results
by part count then net cost (accounting for salvage credit on remnant
material), and returns the best option.

Box constructor and derived properties (Right, Top, Center, Translate, Offset)
had Width and Length swapped — Length is X axis, Width is Y axis. Corrected
across Core geometry, plate bounding box, rectangle packing, fill algorithms,
tests, and UI renderers.
Added FillSpiral with center remnant detection and recursive FillBest on
the gap between the 4 spiral quadrants. RectFill.FillBest now compares
spiral+center vs full best-fit fairly. BestCombination returns a
CombinationResult record instead of out params.

Move 43 root-level test files into feature-specific subdirectories
mirroring the main codebase structure: Geometry, Fill, BestFit, CutOffs,
CuttingStrategy, Engine, IO. Update namespaces to match folder paths.
