🎯 Use case
This file lives under “utils/”, which covers cross-cutting helpers (shell, tempfiles, settings, messages, process input, …). On the API surface it exposes difference, intersects, every, and union — mainly functions, hooks, or classes. What the file header says: Note: this code is hot, so is optimized for speed.
Generated from folder role, exports, dependency roots, and inline comments — not hand-reviewed for every path.
