Refactor BLF to compute NFP paths as Clipper PathsD with offsets
instead of translating full polygons. Add spatial pruning to skip
NFPs that don't intersect the IFP bounds. Clamp placement points
to IFP bounds to correct Clipper2 floating-point drift. Add
progress reporting to simulated annealing. Add debug logging.
