LEGSTECH Optimizer

- NaN composite score: dropna().mean() on empty series returns NaN, nan is truthy so (nan or 0)=nan. Fixed: use None when no MFE data so scorer uses 0.5 fallback instead of propagating NaN. - Analysis stopping: gate WFV was importing from main.execute_run (old CLI code that uses broken runner). Fixed: gate.run_walk_forward now accepts an executor callable from optimizer_loop. - Back to Dashboard opened blank tab: Reports button used window.open(_blank). Fixed: same-tab navigation + history.back(). - NaN in reports card: downstream of composite_score NaN above.
