ltgsmd: Latent True-Score and Target-Population Anchored Geometric SMD

Implements the latent true-score and target-population anchored geometric standardized mean difference (LTG-SMD) framework for two-group effect-size analysis. Provides plug-in estimation, analytic delta-method confidence intervals using a sample fourth-moment plug-in, bias-corrected and bias-corrected-accelerated nonparametric bootstrap confidence intervals with study x group stratification, denominator-sensitivity profiles, and multi-site meta-analytic wrappers. Includes denominator-diagnostic reporting, a pluggable reliability estimator interface, and an explicit interface for specifying the target reference distribution. Companion software to the methodological paper "The Denominator Chooses the Estimand: A Target-Population True-Score Framework for Standardized Mean Differences" (Nakamura, in press, Psychological Methods).
