ShapeProfile.NormalizeEntities called Shape.Reverse() which flipped arc
directions on the original entity objects shared with the CAD view. Switching
to the Program tab and back would leave arcs reversed. Clone entities before
normalizing so the originals stay untouched.
Adds abstract Entity.Clone() with implementations on Line, Arc, Circle,
Polygon, and Shape (deep-clones children). Also adds CloneAll() extension
and replaces manual duplication in PartGeometry.CopyEntitiesAtLocation and
ProgramEditorControl.CloneEntity.

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.

Polygon.OffsetEntity now computes proper miter-join offsets using edge
normals and winding direction, with self-intersection cleanup. CutOff
exclusion zones use geometric perimeter offset instead of scalar padding,
giving uniform clearance around parts regardless of cut angle.

Vector implements IEquatable<Vector> with proper GetHashCode for HashSet usage.
Polygon.FindCrossing uses bounding-box pruning to skip non-overlapping edge pairs.
Helper.DirectionalDistance deduplicates vertices via HashSet, sorts edges for
early-exit pruning, and adds a new array-based overload that avoids allocations.
PartBoundary sorts directional edges and exposes GetEdges for zero-alloc access.

Break deeply nested loop structure into focused helper methods,
reducing max nesting from 5 levels to 2. Uses GetRange/AddRange
for cleaner loop building.

"Length" is more natural than "height" for flat plate materials.
Renames the field on OpenNest.Geometry.Size, Box.Height property,
and all references across 38 files.

Polygon offset at concave corners creates geometry that folds back
through itself. Added RemoveSelfIntersections() to Polygon that
detects non-adjacent edge crossings and removes the smaller loop
at each crossing. Applied to both collision detection and rendering.

Move all projects from Source/ to repository root for simpler navigation.
- Remove External/ dependency DLLs (will use NuGet packages)
- Remove Installer/ NSIS script
- Replace PartCollection/PlateCollection with ObservableList
- Add packages.config for NuGet dependencies
