GLBFP 0.5.2.9000

Updated package authorship and citation metadata for the GitHub development version.

Added sparse-prefix computation for ASH, LBFP and GLBFP grid-count estimators.
Added compute_Di() and compute_di() for fixed-grid leave-one-out self-support scores.
Added lowercase aliases (ash(), lbfp(), glbfp() and corresponding grid functions).
Added as.data.frame() helpers for grid and D_i score objects.
Added plot.glbfp_di() for leave-one-out score diagnostics.
Added a hexagonal package logo and expanded pkgdown article structure.
Added test infrastructure (testthat edition 3) and regression/invariant tests.
Added S3 helpers for summary() and predict() on fit/grid objects.
Added two publication-oriented vignettes (introduction and validation).
Added reproducible benchmark scripts in benchmarks/ and validation helpers in inst/bench.
Added pkgdown and coverage workflows.
Added citation files (CITATION.cff, inst/CITATION) and cran-comments.md.
Added pre-R Journal preparation files in dev/ and rjournal-prep/.

Strengthened input validation (finite numeric checks, shape checks, explicit errors).
Improved numerical robustness in compute_bi_optim() for near-singular covariance matrices.
Fixed plotting methods for irregular custom grids and metadata handling.
Fixed broken references in plot.ASH_estimate().
Reduced duplicated S3 plotting and printing code through shared internal helpers.

Added standard deviation and confidence interval output for *_estimate functions.
