umbral-core 0.0.12

//! gaps4 #40: `umbral::discovered_models!()` — a plugin's `models()` body in
//! one line. The derive records `module_path!()` in its link-time
//! registration, and the macro filters the slice down to the CALLING crate,
//! so this binary sees its own models and none of the framework's.
//!
//! No App boot, no DB — this is a pure registry read, which is exactly the
//! point: `models()` runs before the app exists.
