Description: A unified, tidy, 'ggplot2'-native interface to changepoint
    detection in R. Provides the 'ggcpt' S3 result class with
    'broom'-style tidy/glance/augment methods, 'autoplot()' (with
    confidence intervals, fitted signals, and multivariate facets),
    composable geoms ('geom_changepoint()', 'geom_cpt_segment()',
    'geom_cpt_ci()', 'stat_changepoint()'), and a 'cpt_detect()'
    dispatcher covering over thirty methods with introspection via
    'cpt_methods()': penalised/optimal partitioning (PELT, BinSeg,
    SegNeigh, AMOC, FPOP, CROPS penalty paths, 'fastcpd', change-in-slope
    via 'cpop'), multiscale and search methods (WBS, WBS2, NOT, MOSUM,
    Isolate-Detect, TGUH, SMUCE/HSMUCE with confidence intervals),
    nonparametric and kernel methods ('changepoint.np', 'ecp', 'kcpRS',
    'CptNonPar', sequential 'cpm', self-normalisation via 'SNSeg'),
    Bayesian methods ('bcp', online 'ocp', 'Rbeast'), high-dimensional
    and multivariate methods ('InspectChangepoint', 'ocd',
    'changepoint.geo'), regression breaks ('strucchange', 'segmented',
    'EnvCpt'), and robust detection under drift and autocorrelation
    ('DeCAFS'). Also includes method comparison, batch/panel detection,
    bootstrap stability diagnostics, accuracy metrics, Bayesian posterior
    and run-length plots, interactive rendering, data simulation with
    canonical test signals, and per-method citations.
