Description: Implements Sequential Doubly Robust (SDR) and
        infinite-dimensional Targeted Maximum Likelihood (iTMLE)
        estimators for longitudinal modified treatment policies in
        settings with transitioning states, such as ICU, ward, or
        emergency department care episodes. Treatment is permitted in
        active states and becomes structurally inapplicable after a
        state transition (e.g. discharge or death). Supports asymmetric
        g- and Q-model regularisation, k-fold cross-fitting, and
        pluggable SuperLearner ensembles. Includes specialised
        SuperLearner wrappers (SL.tgt.* and SL.tmle_* families) for the
        iTMLE targeting step, which pass the logit offset as a
        covariate column to preserve correct subsetting during
        SuperLearner cross-validation. Methods based on Diaz et al.
        (2021) <doi:10.1080/01621459.2021.1955691> and Luedtke et al.
