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 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.
