truncProxy 0.2.0

safe_pinv() now falls back to the robust standard SVD driver (dgesvd) when the fast divide-and-conquer driver fails to converge, matching arma::pinv's strategy — divide-and-conquer alone fails routinely on the rank-deficient designs produced by binary covariates. Per-time-step console messages were replaced by a single end-of-call summary, and the rank-deficiency count is returned as n_rank_deficient.
Vectorized the compiled bridge-process recursion with Armadillo matrix operations; roughly 1.5x faster per call, with results identical up to floating-point summation order.
Fixed the handling of pseudo-inverse failures inside the bridge recursion: the integrated bridge process is now carried forward across a failed time step instead of being reset to zero, and the number of failed steps is returned to R (n_pinv_fail), triggering a warning in PQB_estimator() and PQB_IPCW_estimator().
Vectorized B_int_eval() and clamped its interval lookup so evaluation times outside [0, max(qtime)] use the boundary column.
Added validation of the IPCW_weights dimensions in qbridge_IPCW() and NA checks on the IPCW weights in PQB_IPCW_estimator().
Relaxed the regression-test tolerance from 1e-12 to 1e-8 to allow for BLAS summation-order differences.

Initial public package release.
Added PQB_estimator() for proximal weighting estimation under dependent left truncation.
Added PQB_IPCW_estimator() for IPCW-adjusted proximal weighting estimation under dependent left truncation and right censoring.
Added compiled bridge-process routines based on Rcpp and RcppArmadillo.
Added simulation-based examples, regression tests, and GitHub Actions R CMD check workflow.
