New Features and Improvements

  - Added a comprehensive README.md with usage examples, installation
    instructions, and badges (e.g., CRAN status, license).
  - Improved the vignette (validate_skellam.Rmd) with clearer
    explanations, reproducible examples, and better visualizations.

Documentation Updates

  - Revised documentation for skellam.reg to clarify parameter
    definitions, return values, and included practical examples.

Internal Changes

  - Updated vignette-building dependencies (now requires rmarkdown and
    knitr).
  - Minor fixes to ensure compatibility with R CMD check across all
    tested platforms (see cran-results.md).
