Description: Provides threshold sweep methods for Qualitative Comparative
    Analysis (QCA). Implements Condition Threshold Sweep (CTS, for one or
    several conditions), Outcome Threshold Sweep (OTS), and Dual Threshold
    Sweep (DTS) for systematic exploration of threshold calibration effects on
    crisp-set QCA results. These methods extend traditional robustness
    approaches by treating threshold variation as an explicit analytical
    dimension and recording the sufficiency solution obtained at each
    threshold setting. Also provides Fiss (2011)
    <doi:10.5465/amj.2011.60263120> core/peripheral condition classification
    via compute_fiss_core() and generate_fiss_chart(), enabling four-symbol
    configuration charts that distinguish core conditions (present in both
    parsimonious and intermediate solutions) from peripheral conditions
    (intermediate only). Built on top of the 'QCA' package by Dusa (2019)
    <doi:10.1007/978-3-319-75668-4>, with function arguments following 'QCA'
    conventions. Based on set-theoretic methods by Ragin (2008)
    <doi:10.7208/chicago/9780226702797.001.0001> and established robustness
    protocols by Oana and Schneider (2024) <doi:10.1177/00491241211036158>.
    This package supersedes 'TSQCA'; see the NEWS file for migration guidance.
