//! Build script: gzip the bulk CWL signature data into `OUT_DIR`.
//!
//! `data/cwl_signatures.json` is the reviewable, generated source of truth (see
//! `scripts/gen_cwl_signatures.py`), but at ~400 KB it is too large to embed raw.
//! We compress it here so `src/semantic/signature.rs` can `include_bytes!` the
//! ~56 KB gzip artifact and decompress it once on first use. Keeping the
//! compression at build time means a single checked-in file, with no second copy
//! to drift out of sync.
