- FillContext gains a Policy property (init-only) carrying the IFillComparer
- DefaultNestEngine.Fill sets Policy = BuildPolicy() on every context
- RunPipeline now uses context.Policy.Comparer.IsBetter instead of IsBetterFill
- RunPipeline promoted to protected virtual so subclasses can override
- BuildAngles/RecordProductiveAngles overrides delegate to angleBuilder
- RunPipeline calls virtual BuildAngles/RecordProductiveAngles instead of angleBuilder directly
- TODO comment added in group-fill overload for Task 6 Comparer pass-through
