Adds operators.mutate_ruin_recreate: un-divides one wing of a storey and rebuilds it with the same adjacency-aware constructor the seeders use (_assign_adjacency_aware, generalised with a new `scope` param), seeded from the surviving circulation bordering the wing. Gated behind enable_ruin_recreate (default off) / --ruin-recreate, same pattern as reassociate/bridge_circulation. A/B (qpk protocol, DESIGN.md §23): initial uniform-weight run was underpowered (fired ~1/32 children), null. A weight=3.0 follow-up (_MUTATION_WEIGHTS["ruin_recreate"]) showed a statistically significant win on programme-house across 15 seeds (8W/1L/6T, mean fails 7.07->6.00, Wilcoxon p=0.041) but no consistent effect on harbor-house across 8 seeds (3W/2L/3T). Kept default off pending a size-threshold follow-up. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

# f1d A/B: does the ruin-and-recreate LNS move (un-divide one wing of a

# protocol as 8sh/qi6: equal-budget ON vs OFF, both arms finished with the
