Replace stored property setters (BestPartCount, BestDensity, NestedWidth,
NestedLength, NestedArea) with computed properties that derive values from
BestParts, with a lazy cache invalidated on setter. Add internal
ProgressReport struct to replace the 7-parameter ReportProgress signature.
Update all 13 callsites and AccumulatingProgress. Delete FormatPhaseName
in favor of NestPhase.ShortName() extension.

Creates PolygonHelper.cs in OpenNest.Engine.BestFit with ExtractPerimeterPolygon
(returning PolygonExtractionResult with polygon + correction vector) and RotatePolygon.
AutoNester.ExtractPerimeterPolygon and RotatePolygon become thin delegates.
Adds MakeSquareDrawing/MakeLShapeDrawing to TestHelpers and 6 PolygonHelperTests.

Add Optimize method that re-places parts using NFP-based BLF, keeping
the result only if it improves density without losing parts. Fix
perimeter inflation to use correct offset side. Add NfpNestEngine
that wraps AutoNester for the registry. Register NFP engine.

Move AutoNester, BottomLeftFill, NfpCache, SimulatedAnnealing,
and INestOptimizer/NestResult to OpenNest.Engine.Nfp. These are
not yet integrated into the engine registry.
