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.
