Replace stored property setters (BestPartCount, BestDensity, NestedWidth, NestedLength, NestedArea) with computed properties that derive values from BestParts, with a lazy cache invalidated on setter. Add internal ProgressReport struct to replace the 7-parameter ReportProgress signature. Update all 13 callsites and AccumulatingProgress. Delete FormatPhaseName in favor of NestPhase.ShortName() extension. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
