Converts scratch/tune_model.R into a pure tune_lgbm() function, replacing hardcoded winning_params with a fully automated tar_target. Best params (trees=844, depth=3, lr=0.0204, min_n=389) now flow reproducibly into evaluate_final_model() and train_production_model(). PR-AUC improved from 0.165 to 0.198.
