feat(pareto): add Dominance enum and pareto_compare
Implements spec §9.1–9.2:
- `Dominance` enum (Dominates / DominatedBy / NonDominated / Equal).
- `pareto_compare(a, b, objectives)` with the four-step rule: feasible
beats infeasible; among infeasibles, lower violation wins; among
feasibles, compare in minimization orientation via
ObjectiveSpace::as_minimization.
Unit tests cover dominance, dominated-by, non-dominated, equal, the
feasibility tiebreak, and that Maximize objectives are handled correctly
(spec §18.2).
