The deliverable is a single UTF-8 plain-text TypeScript file named keyBy.ts.\n2. It exports keyBy(items: T[], keyFn: (item: T) => string): Record with the exact signature.\n3. It returns a new plain object keyed by keyFn(item), where the last item wins for duplicate keys, and {} for empty input.\n4. It does not mutate the input array or its elements, is deterministic, and uses no imports or external libraries.\n5.
