Description: Implements Goldberg's (2006)
        <doi:10.1016/j.jrp.2006.01.001> bass-ackwards method and modern
        descendants for hierarchical structural analysis. Extracts
        solutions from 1 to k factors using principal component
        analysis (PCA), exploratory factor analysis (EFA), or
        exploratory structural equation modeling (ESEM) engines, then
        characterizes the hierarchy via between-level factor-score
        correlations computed via exact linear algebra (Waller, 2007,
        <doi:10.1016/j.jrp.2006.08.005>) or materialized scores.
        Includes the Forbes (2023) <doi:10.1037/met0000546> extension
        for redundancy pruning and all-levels cross-correlations.
