wbCorr 0.3.0

Release 0.3.0 updates the core within- and between-cluster correlation estimands and inference options.\n\nHighlights:\n- Pairwise-complete centering is now the default for pair-specific within and between correlations.\n- Added centering_rows = "all_available" for workflows that estimate cluster means from all rows available for each variable.\n- Added between_weighting = "equal_clusters" / "cluster_size" with explicit estimand documentation.\n- Added inference = "analytic", "none", or "cluster_bootstrap". Cluster bootstrap resamples top-level clusters and is recommended for publication-level EMA/daily diary inference.\n- Fixed within-person Pearson degrees of freedom to N_pair - k_pair - 1.\n- Removed generated Rcheck/build artifacts from version control.
