//! Tool discovery helpers for optional toolkit capabilities. Use these modules to
//! index hidden candidates, return model-facing discovery results, and construct
//! package deltas for host-approved activation. Searching is data-only; package
//! mutation happens only when a delta is applied. This file contains the policy
//! portion of that contract.
