jgrusewski 8ebb65f27e fix: NaN-safe correlation de-risk in book_series (zero-variance windows) ...

np.corrcoef on a window where a vol-normalized stream is constant (warmup / non-moving stream)
divided by zero std -> RuntimeWarning + NaN in the corr matrix -> ac=NaN -> propagated via chist
into the z-score and could poison leverage L and book with NaN (silent corruption). Fix: correlate
only streams with std>0 in the window, nansum over the actual valid count, fall back to ac=0 when
<2 vary. Verified: no RuntimeWarning (tested with warnings-as-errors), no NaN, identical L/weights.
Affects all scripts importing book_series + the cluster ConfigMap.
