phyloatlas 0.1.0

• Initial CRAN release.
• Four user-facing functions:
  • load_atlas_tree() — fetch a standardized Newick tree from the Phylo-Species Atlas, optionally resolving integer tip IDs to species names via the shared dictionary.
  • list_trees() — data frame of every tree in the atlas with provenance fields (study, year, journal, DOI, coverage).
  • atlas_info() — single-row provenance for a tree by name.
  • atlas_clear_cache() — drop the in-session dictionary/metadata cache.
• In-memory caching of the dictionary and metadata files so repeated calls in a session don’t re-download.
• Fork / mirror support via the phyloatlas.base_url option.
• Bundled offline demo data under inst/extdata/ so examples and tests run without network access.
