Description: Performs exploratory factor analysis on language model
        embeddings of psychological scale items. Embeds item text with
        sentence transformers or other language models, transforms the
        embeddings into item-by-item similarity matrices, and extracts
        latent factor structure via standard exploratory factor
        analysis. Supports embedding-adapted parallel analysis, several
        similarity transforms (atomic reversed, SQuID centering,
        mean-centered Pearson), and fit diagnostics tailored to
        embedding matrices (TEFI, RMSR, CAF, McDonald's omega). The
        underlying methods are documented with full citations in the
        corresponding function help pages. Returns objects compatible
        with 'psych' and 'EFAtools' workflows.
