SSP 1.0.2 (2025-04-23)

Changes requested by CRAN

• Updated cross-references in .Rd files to use explicit package anchors (e.g., \link[ggplot2:ggplot2-package]{ggplot2}) as requested by the CRAN team.
• Removed all \link{} usages without package anchors in documentation files.
• Ensured compatibility with HTML reference manuals.

Documentation improvements

• All .Rd documentation files were migrated to the roxygen2 format.
• Improved consistency and accuracy in the documentation of function arguments and outputs.
• Added missing imports in the NAMESPACE to fix visibility issues (ggplot, geom_point, specnumber, etc.).
• Removed unused @importFrom tags and documented only necessary dependencies.

Code adjustments

• Replaced use of rel() in plot_ssp() to avoid dependency on grid::rel, which is not exported.
• Reformatted long lines in examples to comply with CRAN’s 100-character limit.

Testing and validation

• devtools::check() returns 0 errors | 0 warnings | 1 notes (only minor ones related to timestamp verification).
