The pattern bounding box already computes max(upper) - min(lower), so the
manual loop was redundant. Extract the N×N pair distance loop into a static
FindMaxPairDistance helper. Drop pre-cached edge arrays since GetEdges()
returns stored references with zero allocation.

Also fix missing using for FillHelpers in FillLinear and FillExtents,
and update callers (CompactorTests, PatternTileForm) for the new
Vector parameter.

Move known-good pruning check before sweep/ML to avoid wasted work,
extract ContainsAngle, NeedsSweep, AddSweepAngles, ApplyMlPrediction,
and BuildPrunedList so Build reads as a clear pipeline.

FillExtents vertical copy distance was not clamped, allowing rows to be
placed overlapping each other when slide calculations returned large
values. Clamp to pairHeight + partSpacing minimum, matching FillLinear.
Also add FillStrategyRegistry.SetEnabled() to restrict which strategies
run — useful for isolating individual strategies during troubleshooting.

Promotes btnRemovePlate to a field and toggles Enabled based on
plate count in add/remove event handlers.

DensityBar: clamp rounded rect radius for small fill widths to avoid
GDI+ artifacts at very low density values.
PhaseStepperControl: use float arithmetic for circle spacing to
handle DPI-scaled widths evenly.

6-task plan covering PhaseStepperControl, DensityBar, form rewrite,

Single-part group fills now delegate to Fill(NestItem) which runs
the full strategy pipeline, eliminating ~70 lines of duplicated
manual phase logic. Multi-part group fills retain the linear
pattern fill (unique to multi-part groups).
PairFiller now references FillHelpers directly instead of
bouncing through DefaultNestEngine helper methods.

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

Move fill algorithms to OpenNest.Engine.Fill namespace:
FillLinear, FillExtents, PairFiller, ShrinkFiller, Compactor,
RemnantFiller, RemnantFinder, FillScore, Pattern, PatternTiler,
PartBoundary, RotationAnalysis, AngleCandidateBuilder, and
AccumulatingProgress.
Move strategy layer to OpenNest.Engine.Strategies namespace:
IFillStrategy, FillContext, FillStrategyRegistry, FillHelpers,
and all built-in strategy implementations.
Add using directives to all consuming files across Engine, UI,
MCP, and Tests projects.

DefaultNestEngine.Fill(NestItem, ...) now delegates to RunPipeline
which iterates FillStrategyRegistry.Strategies in order.
Removed: FindBestFill, FillRectangleBestFit, QuickFillCount.
Kept: AngleCandidateBuilder, ForceFullAngleSweep, group-fill overload.

Wraps FillLinear in an IFillStrategy, sweeping all AngleCandidates
from SharedState (falling back to 0° and 90°) in both directions and
recording AngleResults for UI inspection.

Wraps FillExtents in an IFillStrategy, trying both bestRotation and
bestRotation+90° angles and picking the better result. Reads
BestFits from SharedState (populated by PairsFillStrategy) to allow
FillExtents to search the best-fit cache for improved pair geometry.

Wraps FillBestFit rectangle packer in an IFillStrategy so the rect
best-fit phase participates in the pluggable pipeline.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Wraps PairFiller in an IFillStrategy so the pairs phase participates
in the pluggable pipeline. Stores BestFitResults in SharedState for
downstream strategies (Extents) to reuse.

Move BuildRotatedPattern and FillPattern static methods into a new
public FillHelpers class in Strategies/. DefaultNestEngine retains
internal static forwarding stubs so existing callsites are unchanged.

Replace single preview PlateView with two stacked previews showing
horizontal and vertical FillLinear results. Each has a label showing
the part count. Apply uses the direction with more parts.
