Description: Comprehensive instrumental variables and GMM estimation with
    automatic diagnostics, inspired by the 'Stata' command 'ivreg2' of Baum,
    Schaffer, and Stillman (2003) <doi:10.1177/1536867X0300300101> and Baum,
    Schaffer, and Stillman (2007) <doi:10.1177/1536867X0800700402>. Supports
    2SLS, LIML, Fuller, k-class, two-step efficient GMM,
    and continuously-updated (CUE) estimators. Provides classical, robust,
    cluster-robust, HAC, and Driscoll-Kraay standard errors. Reports weak
    identification, underidentification, overidentification, and endogeneity
    tests at estimation time. All outputs are verified against 'Stata' within
    tight numerical tolerances.
