Change Nest() to decide fill vs pack based on total area coverage
instead of qty != 1. Items covering < 10% of the plate are packed,
so large parts get prime position and small low-qty parts fill gaps.
Qty=2 items are placed as interlocking best-fit pairs in remnant
spaces after the main pack phase, rather than as separate rectangles.
- Add ShouldFill() capacity-based heuristic
- Split pack phase: regular items pack first, then pairs
- Add PlaceBestFitPairs() for Phase 3 remnant pair placement
