    … efficient _evaluate_by_index for GMAE.
    
    Additional methods added :- 
    _compute_pseudo_values: Computes the jackknife pseudo-values for the Geometric Mean Absolute Error (GMAE) metric, estimating the influence of each observation on the overall metric.
    
    _evaluate: Evaluates the GMAE metric on given inputs, providing the overall metric value. This method is the core logic called from the evaluate method and computes the arithmetic mean over time points by default.
