Package-hygiene pass, mirroring the recent revolver/INCOMMON cleanup:
Rewrote Title to follow the PKG: Title Case convention and fixed a typo (“packege”) and duplicated ggplot2/dplyr entries (listed in both Depends and Imports) in DESCRIPTION.
Rewrote the Description field and the README opening paragraph to a consistent style, and reconciled the TOSCA acronym (Timing Of Somatic Events in Cancer) between DESCRIPTION and README.
Fixed URL to point to a single canonical pkgdown site and added a BugReports field.
Added an R-CMD-check GitHub Actions workflow (none previously existed), skipping vignette building/checking since the vignettes run full Stan inference pipelines not suited to CI.
Modernized the pkgdown workflow to deploy via pkgdown::deploy_to_branch() instead of a third-party action, dropping pull-request builds.
Untracked stray files that had been committed by mistake (.DS_Store in six locations, the TOSCA.Rcheck/ build-check output, and the built TOSCA_0.1.0.tar.gz) and extended .gitignore to prevent recurrence.
Resized the package logo to hex-sticker proportions (208x240, preserving aspect ratio).
Added R-CMD-check/pkgdown/Lifecycle/GitHub-stars badges to README.
