IDConverter 0.4.0

CRAN Resubmission

• Bundled real data files in data/ (tcga, icgc, pcawg_full, pcawg_simple) instead of empty placeholders — core functions now work fully offline.
• load_data() now loads bundled datasets directly via utils::data(), falling back to Zenodo download only for non-bundled data.
• Added LazyDataCompression: xz to DESCRIPTION to comply with CRAN policy for lazy data larger than 1 MB.
• Wrapped parse_gdc_file_uuid() examples in \dontrun{} to prevent network access during R CMD check.
• ls_annotables() and convert_hm_genes() now handle offline state gracefully with informative messages.
• Updated Zenodo record URL from 6342397 to 10360995 (/records/ format).
• Added biocViews: field to DESCRIPTION for Bioconductor compatibility.

New Features

• Added build_annotables() — builds up-to-date gene annotation tables directly from Ensembl BioMart using recipes from the annotables package. Supports 11 organisms (including dog, zebrafish, pig) with mirror fallback and local caching. Requires biomaRt (Bioconductor).
• Added pair_gdc_samples() — pairs tumor-normal samples from GDC manifest files. Automatically classifies tumor vs normal by TCGA barcode, prefers blood-derived normals, and generates all tumor-normal combinations per case. (#7)
• convert_hm_genes() now supports ce11 (C. elegans) and T2T (human T2T/CHM13) genome builds.
• Added resolve_gene_aliases() — resolves outdated or alternative gene symbols (e.g., “MLL” -> “KMT2A”) using Ensembl synonym data. Requires build_annotables(include_synonyms = TRUE) for source data. (#11)
• build_annotables() gains include_synonyms parameter to fetch external_synonym from Ensembl BioMart.
• Added convert_hm_orthologs() — converts gene symbols or Ensembl IDs between human and mouse via Ensembl orthology (e.g., TP53 <-> Trp53). Supports high-confidence filtering and cached queries.

Other Changes

• Repository migrated from ShixiangWang/IDConverter to WangLabCSU/IDConverter. All URLs updated in DESCRIPTION, README, pkgdown config, and documentation.
• All Rd files regenerated via devtools::document() for consistency.
• Added IDConverter.Rcheck/ to .gitignore and .Rbuildignore.
