- Convert static class to instance with private constructor; shared
parameters (template, plateOptions, salvageRate, minRemnantSize,
progress, token) become fields, eliminating parameter threading
across all private methods (10→3 params on Nest entry point stays
unchanged; private methods drop from 7-9 params to 1-2)
- Extract FillAndPlace helper consolidating the repeated
clone→fill→add-to-plate→deduct-quantity pattern (was duplicated
in 4 call sites)
- Merge FindScrapZones/FindViableRemnants (98% duplicate) into single
FindRemnants(plate, minRemnantSize, scrapOnly) method
- Extract ScoreZone helper and collapse duplicate normal/rotated
orientation checks into single conditional
- Extract CreateNewPlateResult helper for repeated PlateResult
construction + PlateOption lookup pattern
