jgrusewski 25ff1d4195 fix(sp16): floor Wiener-α at 0.4 for non-stationary control loops ...

Wiener-optimal α minimizes MSE for stationary stochastic signals.
The min_hold_temp / hold_cost_scale loops track a target driven by
the adapting policy itself — non-stationary by construction.

Empirical evidence: train-multi-seed-b5gmp sha 641aa0dfd, Fold 1
collapse Sharpe 88.65 → 55.55 because α decayed to 0.248 by HD4
and could no longer track the climbing overrun signal.

Pearl: pearl_wiener_alpha_floor_for_nonstationary (memory).
