//! rustyomestats — genome statistics, codon density, and U50-family
//! assembly metrics.
//!
//! Modules:
//! * [`io_utils`] — FASTA discovery / loading
//! * [`stats`] — length / GC / N-L stats (polars output)
//! * [`codon`] — 6-frame translation + absolute/predicted codon density
//! * [`fgs`] — FragGeneScanRs subprocess wrapper for predicted ORFs
//! * [`u50`] — Castro et al. (2016) N50/U50 assembly metrics from a
//! reference FASTA + mapped-contigs BED
