xplaineff 0.1.0

• Package renamed to xplaineff for CRAN submission (no issue).
• AleStrategy categorical splits now apply ordered-prefix partitions consistently in fitted trees and display category sets for those splits (no issue).
• AleStrategy now accepts a bare prediction function as model in the default ALE prediction path (no issue).
• AleStrategy split search now skips ALE effect components with numerically zero heterogeneity while keeping all split candidate features available (no issue).
• AleStrategy and PdStrategy now prune negligible effect components during split search while preserving all split candidate features and full effect grids (no issue).
• AleStrategy and PdStrategy now default to auto precompute engine selection while keeping explicit cpp and r engines as compatibility options (no issue).
• AleStrategy now supports categorical_split = "exhaustive" for level-set searches over categorical ALE split candidates while retaining ordered-prefix splits as the default (no issue).
• AleStrategy split search now uses the bias-corrected self-gain ranking objective for ALE self-feature splits (no issue).
• AleStrategy now uses only the selected split’s objective rows when multiple ALE split candidates tie (no issue).
• calculate_ale() and calculate_ale_fast() now preserve fractional interval bounds for integer features and restore shared prediction scratch data between features (no issue).
• calculate_ale_fast() now normalizes custom predict_fun outputs like the R ALE path and errors on prediction length mismatches (no issue).
• calculate_pd() now routes custom predict_fun calls through the cached R-side PD stack to avoid slow data-frame reconstruction in the C++ stacker (no issue).
• calculate_pd() now uses a row-major full-ICE prediction layout for native ranger regression models under pd_engine = "auto" (no issue).
• compute_ice_r() now preserves fractional grid values for cached integer features in the PD R backend (no issue).
• default_predict_fun() now uses direct regression prediction paths for native ranger, native and mlr3 rpart, and native and mlr3 xgboost models when no custom predict_fun is supplied. It also skips redundant feature subsetting for already aligned prediction data (no issue).
• extract_split_info() keeps categorical split level sets out of the default summary table (no issue).
• extract_split_info() now omits internal split timings by default and can include them with include_timing = TRUE (no issue).
• PdStrategy now avoids redundant re-centering for already centered full-grid PD matrices and uses a cache-friendly exact split-search layout (no issue).
• PdStrategy now supports categorical_split = "exhaustive" for level-set searches over categorical PD split candidates while retaining one-vs-rest as the default and guarding large level counts with max_exhaustive_levels (no issue).
• plot_tree_pd() now displays categorical split conditions as category sets instead of equality labels (no issue).
• plot_tree_pd() now names returned node plots with actual tree node ids instead of depth-local positions (no issue).
• prepare_split_data_pd() now infers effect features from precomputed PD/ICE results when feature_set is omitted and still uses all non-target columns as split candidates (no issue).
