feat(XS01): affina con blend di lookback [30,90] — FULL 0.80->1.10, portafoglio 1.41->1.48

Come TP01 fonde gli orizzonti, XS01 ora fonde 30g+90g del momentum cross-sectional (z-score per
lookback, mediato). Sweep: [30,90] e' il sweet spot (fonde i due singoli robusti, anti-overfit):
XS01 standalone FULL 0.80->1.10, DD 21%->14%, corr a TP01 -0.06->-0.12, 100% anni+. Portafoglio
TP01 70 + XS01 30: FULL Sh 1.41->1.48, DD 5.2%->4.6%, ~€/g 1.65->1.78; hold-out 1.15->1.06 (calo
marginale dentro il rumore). Piu' robusto (due orizzonti) + diversifica meglio -> promosso.

sleeves.XS_CFG lookbacks=(30,90), engine _xsec_returns usa lo score blended. 12 test ok.
