//! `lean-ctx embeddings` — semantic-embedding runtime management (GH #732).
//!
//! The embedding engine loads ONNX Runtime dynamically. `provision` performs
//! the **explicit, consent-gated** download of the official CPU runtime into
//! the managed artifact layout; `status` shows what the resolver would use.
//! Nothing here runs implicitly — the policy decided on #732 is "no silent
//! download at first tool call, ever".
