Description: A comprehensive toolkit for Statistical Process Control
        (SPC) that combines the rigor of classical Shewhart methodology
        with modern tidyverse-native interfaces. Provides classical
        control charts for variables (I-MR, Xbar-R, Xbar-S) and
        attributes (p, np, c, u), as well as regression-based control
        charts for processes with trend. Includes Nelson runs tests,
        Average Run Length (ARL) simulation, process capability indices
        with bootstrap confidence intervals, Box-Cox transformation
        guidance, and a clean Phase I / Phase II workflow. All chart
        objects integrate with broom via 'tidy', 'glance' and 'augment'
        methods. References: Shewhart (1931, ISBN:0-87389-076-0);
