//! NER provider adapters for mnem.
//!
//! Ships two built-in providers:
//!
//! - [`RuleNer`] — capitalized-phrase heuristic (Person / Organization),
//! zero dependencies, always available.
//! - [`NullNer`] — no-op, emits nothing. Selected via
//! `[ner]\nprovider = "none"`.
//!
//! The [`open`] factory constructs the right implementation from a
//! [`NerConfig`]. Wire [`NerConfig`] into [`mnem_ingest::IngestConfig`]
//! and call [`open`] during pipeline construction.
//!
//! ## Entity label strings
//!
//! Entity labels are free-form strings — there is no closed vocabulary.
//! Each [`NerProvider`] implementation returns whatever label strings it
//! chooses (e.g. `"Entity:Person"`, `"Entity:Chemical"`, etc.). The
//! mnem node graph stores the raw label string as the node's `ntype`.
