//! Knowledge-map producers (pure-Rust).
//!
//! Three scanners that fill the symbol/call/feature/git-heat tables in
//! the iceberg warehouse so the viz layer can draw a complete map
//! without ever invoking `cargo` or `rustdoc`:
//!
//!  - [`symbols::scan_repo`]  — walks every `Cargo.toml`, parses every
//!    `.rs` file with `syn`, emits one row per discovered item plus
//!    one row per call expression and one row per `#[cfg(...)]` attr.
//!  - [`git_heat::scan_repo`] — uses `gix` to walk HEAD's commit graph
//!    and aggregate per-file commit count / author count / recency.
//!
//! Both producers are idempotent — every scan generates a fresh
//! `snapshot_id` (UUID v4) and appends. The renderer reads the latest
//! snapshot per repo.
