PairFiller now returns PairFillResult (Parts + BestFits) instead of
using a mutable BestFits property. Extracted EvaluateCandidates,
TryReduceWorkArea, and BuildTilingAngles for clarity. Simplified the
candidate loop by leveraging FillScore comparison semantics.
Removed FillRemainingStrip and all its helpers (FindPlacedEdge,
BuildRemainingStrip, BuildRotationSet, FindBestFill, TryFewerRows,
RemainderPatterns) from FillLinear — these were a major bottleneck in
strip nesting, running expensive fills on undersized remnant strips.
ShrinkFiller + RemnantFiller already handle space optimization, making
the remainder strip fill redundant.

When the first pair candidate places more parts than needed (e.g., 17
when target is 10), sort by BoundingBox.Top, trim from the top until
exactly targetCount remain, and use that Top as the new work area
height. All subsequent candidates fill this smaller area, dramatically
reducing fill time.

PairEvaluator already computes OptimalRotation via RotatingCalipers on
the pair's convex hull, but PairFiller.EvaluateCandidate only passed
hull edge angles to FillPattern. Now includes the optimal rotation
angle (and +90°) so tiling can use the mathematically tightest fit.

Extract magic numbers into named constants (MaxTopCandidates,
EarlyExitMinTried, etc.), extract candidate evaluation into
EvaluateCandidate method, and expose BestFits property so
PairsFillStrategy can reuse without redundant BestFitCache call.

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.
