Pin committed fulfillment and exact placement poses for Default, Strip,
Vertical Remnant, and Horizontal Remnant through the production
PlateNesterFactory + NestJobRunner path, plus deterministic poses for
OrderedPlateNester via its StockLadder wiring (no legacy counterpart) and
authoritative progress-stage sequences for StockLadder and
FixedStrategyNestingEngine. Captured at 42bbde7 (post ShrinkFiller axis
fix); these fixtures are the regression net for the legacy-engine removal.
Note: Strip is pinned on a rectangle-variety job. On dense mixed-shape
jobs the iterative shrink path intermittently proposes overlapping
candidates (pre-existing scheduling nondeterminism), so its mixed-geometry
layout is deliberately not pinned.
