Phase 0.2 of the mutation-testing campaign. Adds a module gated on
#[cfg(feature = "async")] that, for every algorithm with a run_async,
asserts that the async runner produces the same result as the sync
runner given the same Config + seed + problem.
Before: nothing exercised run_async, so cargo mutants survived
'replace run_async body with OptimizationResult::new()' and every
comparison/arithmetic mutant inside the async loop for every
async-capable algorithm — about 25-30 algorithms * 5-10 mutants each.
After: every such mutant is killed because the parity test detects
any divergence in best.evaluation.objectives or pareto-front
objective tuples.
