bamp 2.2.0

• Effects (age, period, cohort) are now computed automatically inside bamp() and stored in the returned object (model$effects), so a separate call to effects.apc() is no longer needed for the default median summary.
• Fixed bug in effects.apc(): cache check was looking for x$effect (singular) instead of x$effects (plural), and referenced an undefined variable in the cache condition.
• MCMC chains now use warm starts: on a restart the previous sample values are used as initial values, reducing burn-in time for automatic convergence checking. First-run behaviour is unchanged.
• Fixed bug in cohort heterogeneity hyperparameter check (cohort="rw2+het" was not recognized correctly).
• Fixed typo in period_covariate handling that silently prevented vector coercion.
• Fixed checkConvergence(): cohort convergence check used age hyperparameter instead of cohort hyperparameter.
• Fixed hyperparameter display in checkConvergence() info output.
• Fixed memory leaks in C++ MCMC code (raw pointer allocations per iteration).
• Fixed GetRNGstate/PutRNGstate pairing in random number generation.
• Added Cholesky decomposition error check with informative message.
• Replaced fork-based mclapply with socket-based makeCluster/parLapply for reliable parallel execution on all platforms, including macOS GUI environments (RStudio). Falls back to sequential if cluster setup fails.
• MCMC chains that fail due to numerical errors are now discarded cleanly instead of continuing with corrupted values.
• Cholesky decomposition now recovers from non-positive-definite precision matrices (common with RW2 priors during tuning) by adding increasing diagonal regularization and retrying, instead of aborting the chain.
• Added unit tests.
• Updated CITATION to use bibentry().
