//! Rule configuration and disk-descriptor model.
//!
//! A *rule* is a markdown instruction fragment an organisation ships to its
//! agents through a plugin bundle. [`DiskRuleConfig`] is the per-rule on-disk
//! descriptor at `rules/<id>/config.yaml`, naming the markdown file that
//! carries the rule text. Unlike the skill and hook descriptors this one is
//! also serialisable: the marketplace importer writes these files from an
//! Anthropic `rules/*.md` tree, so read and write share one shape.
