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,
