Box constructor and derived properties (Right, Top, Center, Translate, Offset)
had Width and Length swapped — Length is X axis, Width is Y axis. Corrected
across Core geometry, plate bounding box, rectangle packing, fill algorithms,
tests, and UI renderers.
Added FillSpiral with center remnant detection and recursive FillBest on
the gap between the 4 spiral quadrants. RectFill.FillBest now compares
spiral+center vs full best-fit fairly. BestCombination returns a
CombinationResult record instead of out params.

Adds PerimeterToAreaRatio (perimeter / area) as a spacing sensitivity
indicator for ML feature extraction.

Add FeatureExtractor for computing geometric part features (convexity,
aspect ratio, circularity, bitmask) and BruteForceRunner for generating
training data by running the fill engine and recording results.
