+//! CLI binary that regenerates `.huskies/source-map.json` from scratch.
+//!
+//! Usage: `source-map-regen [--project-root <path>]`
+//!
+//! Scans every tracked Rust and TypeScript file in the project via `git ls-files`,
+//! extracts public item signatures, and writes a fresh sorted JSON map. The output
+//! is byte-identical across runs on the same source tree (deterministic).
+//!
+//! Intended to be called from the pre-commit quality gate (`script/check`) so that
+//! every commit captures an accurate, stale-entry-free snapshot of the source map.
