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 Rubinson et al. (2019)
    <doi:10.1177/00491241211036158>. This package supersedes 'TSQCA'; see
    the NEWS file for migration guidance.
