I added an RSetLike<T> structural type to support any “set-like” object with .has() (not just real Sets) so that there's no reliance on ReadOnlySetLike for older typescript versions

I reimplemented the new set methods using TS overloads so they will accept "Set-like" objects.

Added asIterable() helper (with hasIterator / hasForEach) to normalize Set or Set-like inputs. This shouldn't change any existing runtime behavior with the exception of widening what proxySet accepts as "set-like" objects. asIterable(other) returns other unchanged when it has [Symbol.iterator] so it should be a no-op for existing stuff.
