mdbook-lint 0.16.0

//! CLI-facing helpers for the global `ignore-paths` configuration.
//!
//! The matching semantics live in `mdbook_lint_core::ignore`, shared with the
//! mdBook preprocessor and the MDBOOK005 rule so the three cannot drift. This
//! module just adapts that shared matcher to the CLI's file-filtering use case.
