Description: Provides threshold sweep methods for Qualitative Comparative 
    Analysis (QCA). Implements Condition Threshold Sweep-Single (CTS-S), 
    Condition Threshold Sweep-Multiple (CTS-M), 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 
    exploratory tool for discovering causal structures. 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.
