driver.search()/search_staged() gain enable_shape_repair (default off),
mirroring the enable_reassociate clean-toggle pattern: only builds a
fitness.Fitness instance and passes it to operators.mutate() when
enabled, so shape_rotate/deslim (7fm) can actually be selected mid-GA
instead of always no-opping on fit=None.
Full A/B sweep (harbor-house, budget=1M, 4 seeds) shows no improvement:
mean fails 14.50 (off) vs 14.75 (on), within seed noise. Confirms 7fm's
finish-time finding at in-search scale — these operators don't rescue
harbor-house's residual fails even with GA selection pressure.
