Implements a sealed adapter class that forces a fixed IPlateNester strategy onto any NestJob, overriding the job's own PlacementStrategy while preserving MaxPlates. Delegates all multi-plate allocation and stock selection to NestJobRunner. This allows single-plate nesting strategies to compete as full whole-job INestingEngine solvers in benchmarks, enabling comparative performance testing of placement algorithms across various job configurations.
