ccd402c50f refactor: simplify NestProgress with computed properties and ProgressReport struct 
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.

71f28600d1 refactor: extract PolygonHelper from AutoNester for shared polygon operations 
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.

a04586f7df feat: add AutoNester.Optimize post-pass and NfpNestEngine 
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.

d9d275b675 feat: improve BLF with Clipper paths, spatial pruning, and progress 
Refactor BLF to compute NFP paths as Clipper PathsD with offsets
instead of translating full polygons. Add spatial pruning to skip
NFPs that don't intersect the IFP bounds. Clamp placement points
to IFP bounds to correct Clipper2 floating-point drift. Add
progress reporting to simulated annealing. Add debug logging.

9411dd0fdd refactor: extract PlacedPart/SequenceEntry types, add IFP caching 
Move PlacedPart to its own file. Replace tuple-based sequences with
SequenceEntry struct for clarity. Add IProgress parameter to
INestOptimizer. Add IFP caching to NfpCache to avoid recomputing
inner fit polygons for the same drawing/rotation/workArea.

495ee6f0c3 refactor(engine): move NFP code to OpenNest.Engine.Nfp namespace 
Move AutoNester, BottomLeftFill, NfpCache, SimulatedAnnealing,
and INestOptimizer/NestResult to OpenNest.Engine.Nfp. These are
not yet integrated into the engine registry.

0cba528591 docs: update README with accurate features and add roadmap 
Remove NFP pair fitting claim from features (not yet integrated).
Qualify lead-in/lead-out as engine-only (UI coming soon).
Mark --autonest CLI option as experimental. Add Roadmap section
with planned work: NFP nesting, lead-in UI, sheet cut-offs,
post-processors, and shape library UI.

Add documentation maintenance instruction to CLAUDE.md requiring
README.md and CLAUDE.md updates when project structure changes.
