Pure-Rust Customizable Contraction Hierarchies (CCH): build, customize in parallel, and serve fast shortest-path distance, many-to-many matrix, and path queries on road networks
// Phase-2 construction helpers — consumed by Tasks 9–10 (CCH structure
// building and customization). The items are `pub(crate)` staging: they have
// no non-test callers yet, so suppress the dead_code lint here rather than
// throughout each file.
