1//! Index path utilities — project-root normalization and graph match keys.
2//!
3//! Extracted from the deprecated `graph_index` module (#682) so these pure path
4//! helpers survive the removal of the in-memory `ProjectIndex` graph. They have
5//! no dependency on any graph backend — only `pathutil` and std.
