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.

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.

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.

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.
