On the compatible read path, seq and qual are now built directly in C as DNAStringSet / PhredQuality objects from the packed BAM byte buffer (via the IRanges/XVector C-callable constructors), avoiding a character round-trip. Output remains byte-identical to Rsamtools::scanBam.
Added an end-to-end workflow benchmark harness under inst/benchmarks/ (coverage → bigWig and ATAC fragment-size QC) and a self-contained benchmark-results vignette.
Bug fixes
GAlignments output now carries the BAM-header sequence lengths in its Seqinfo. Previously the seqlengths were NA, so coverage() extended each seqlevel only to its maximum end and export.bw() wrote truncated chromosome sizes, diverging from GenomicAlignments::readGAlignments.
Force-load the C-callable providers (S4Vectors, IRanges, XVector, Biostrings) and GenomicAlignments in .onLoad, so the compatible seq/qual and GAlignments paths resolve their constructors and classes on fresh SnowParam SOCK workers.
Documentation
Refreshed the README with the latest benchmark results (read-pattern and end-to-end workflow speedups) and Bioconductor installation instructions.
