//! Directory names the scanner refuses to descend into.
//!
//! Ported verbatim from npkill's `src/core/constants/global-ignored.constants.ts`.
//! Rule: if a directory name appears in this set AND is NOT itself a target,
//! the scanner skips recursion into it. A name in this set CAN still be a
//! target — that case wins (so a profile that lists `node_modules` will still
//! match `node_modules` directories).
