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.

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 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.
