Anofox Statistics Batch

AI-ready batch and per-group model fitting for the anofox_statistics DuckDB extension — training thousands of regression models in a single SQL query. Covers the *_fit_predict_by table macros (ols_fit_predict_by, huber_fit_predict_by, ransac_fit_predict_by, theil_sen_fit_predict_by, ridge_fit_predict_by, elasticnet_fit_predict_by, wls_fit_predict_by, rls_fit_predict_by, bls_fit_predict_by, alm_fit_predict_by, poisson_fit_predict_by, binomial_fit_predict_by, logistic_fit_predict_by, negbinom_fit_predict_by, gamma_fit_predict_by, tweedie_fit_predict_by, pls_fit_predict_by, isotonic_fit_predict_by, quantile_fit_predict_by, bayesian_ridge_fit_predict_by, ard_fit_predict_by, passive_aggressive_fit_predict_by, lm_dynamic_fit_predict_by) with split := and order_by :=, the per-group long-table macros <model>_tidy_by and <model>_glance_by (25 models), ols/wls/GLM _augment_by, <model>_partial_residuals_by, <model>_prediction_by (23 models), <model>_effects_by (marginal effects), <model>_rolling_tidy_by (rolling coefficients), ridge/elasticnet/lars_path_by, ridge/elasticnet_cv_by, ridge/elasticnet_nested_cv_by, quantile_process_by, acf_by / pacf_by, kaplan_meier_by, roc/pr/calibration_curve_by and pairwise_t_test_by / tukey_hsd_by / dunn_test_by, per-group aggregate fitting with GROUP BY plus predict / tidy / glance on the per-group model structs, the *_fit_predict_agg aggregates, rolling *_fit_predict window functions, the glmm_fit_by / eb_shrink_by / aid_by macros, and scaling patterns for fitting a separate model per segment / SKU / cohort over large panels. Also glmm_tidy_by / glance_by / augment_by, ols_anova_by, mediation_by, p_adjust_by, ridge / elasticnet_nested_cv_by, the split := rule and order_by := for rls_tidy_by. Use when the task is "fit one model per group" at scale, or "give me a coefficient / fit / residual / prediction table per group", rather than a single global fit.
