//! Local workspace find tools: [`grep_search`](GrepSearchTool) and [`glob_search`](GlobSearchTool).
//!
//! This module is named `find` to distinguish **local lookup** from network search (the `web` feature).
//! Use [`FindContext`] for the default scan root (canonical). Omitted `path` in tool calls starts
//! from that root. Relative `path` joins against it; absolute paths are accepted as-is.
