* `isDisjointFrom(target, source)`
*
* Checks if the `target` set is disjoint from the `source` set (i.e., they share no common values). Returns `true` if the sets have no intersection, `false` otherwise.
*
* ```ts
* isDisjointFrom(new Set([1, 2]), new Set([3, 4])); // true
* isDisjointFrom(new Set([1, 2]), new Set([2, 3])); // false
* ```
*
* ```ts
* pipe(new Set([1, 2]), isDisjointFrom(new Set([3, 4]))); // true
* pipe(new Set([1, 2]), isDisjointFrom(new Set([2, 3]))); // false
* ```
