jgrusewski cb402ab81f feat(surfer): crypto carry+momentum sweep — FIRST real edge (funding carry) ...

Batch 2 of the deflated signal sweep: cross-sectional funding carry + momentum on
28 major Binance USDT perps (2019-26, funding baked into return, 10bp cost, deflated
by cumulative 25 trials). XS_carry_7 = Sharpe +0.82, IS+0.77/OOS+0.93 (consistent),
CPCV-median +0.78 (robust across 45 paths), DSR 0.71. First signal all session that is
positive + IS/OOS-consistent + CPCV-median-positive. Develop-grade met, not yet deploy
(DSR<0.95, 5th-pct<0). Caveats: survivorship (current majors), confirm point-in-time.
Forward-paginated funding fetch (fundcov ~1.0).
