Modules

@fast-china/utils is the only public entry and exposes every API as a named export. Source modules remain separate in dist/ so modern bundlers can remove unused exports; those internal files are not public package subpaths.

The object module includes dependency-free deep cloning and equality plus predicate-based property selection. Array utilities include a SameValueZero symmetric difference, while once preserves the first return value, Promise identity, or synchronous error.
