Description: Implements Bayesian quantile regression for count data using the
    jittering technique for discrete data smoothing and an asymmetric Laplace
    distribution likelihood. Supports adaptive variable selection via a
    random-bridge penalty with a beta prior on the power parameter, as well as
    fixed-bridge and Lasso penalties. Utilizes Markov chain Monte Carlo with
    Gibbs sampling and adaptive Metropolis-Hastings algorithms for posterior
    inference, provides Gelman-Rubin convergence diagnostics, and predicts
    conditional quantiles for count responses. Methodology and applications are
    based on the following key references: Luo, Zhou, Hu, and Li (2026, Journal of
    Mathematics, 2026:1543166, <doi:10.1155/jom/1543166>), Koenker and Bassett
