oxicode-catalog 0.73.0

//! Build script for oxicode-catalog.
//!
//! The catalog owns the embedded models.dev snapshot
//! (`data/catalog/_snapshot.json.gz`), included via `include_bytes!` at
//! compile time in `catalog/materialize.rs`. No runtime IO is needed for the
//! catalog.
//!
//! # CI / reproducible builds
//!
//! Set `OXICODE_CATALOG_SNAPSHOT=path` to inject a specific snapshot file
//! (e.g., from CI artifacts). Otherwise, the committed `_snapshot.json.gz`
//! is used by default.
//!
//! Model data © [models.dev](https://models.dev) (MIT).
