jgrusewski c318ffa30a fix(ml): 3 hyperopt objective bugs — sliding windows, tanh normalization, adaptive tau ...

1. Walk-forward windows: replaced 3 non-overlapping with sliding (50% overlap, ~5 windows).
   Aggregation changed from mean-0.5*std to median-0.5*IQR for outlier robustness.

2. Composite score: tanh normalization prevents Calmar ratio scale dominance
   (0.02% drawdowns → values in thousands drowning out Sharpe/Sortino).

3. Q-value overestimation: new Prometheus gauge foxhunt_training_q_overestimation_ratio,
   warning log when ratio>10 or q_mean>5, adaptive tau doubles when Q-mean growth>0.5/epoch
   (capped at 0.01), decays back when stable.

2742 tests pass, 0 failures.
