jgrusewski 292147090f feat(scripts): lower-frequency directional IC harness (intraday + daily + backtest)
Tests minutes-to-days directional predictability on ES OHLCV-1m where moves
dwarf the spread: momentum/reversion IC (Pearson/Spearman/NW-t/OOS) + a
non-overlapping daily contrarian backtest (IS/OOS Sharpe).

Verdict on 2y ES (2024-25): intraday IC~0; daily mean-reversion IC looks large
(-0.44 Spearman @20d) but is overlap-inflated + regime artifact -- honest
non-overlapping backtest sign-flips IS<->OOS => no stable edge. Confirms no
robustly capturable directional edge on 2y ES across all measured horizons.
