feat: support for recursive structures

[DemonHa]

The current Clone, Check and Cast functions does not handle recursive (circular) structures. When an object references itself, the function runs into infinite recursion and throws a Maximum call stack size exceeded error.

const a = { x: 1 };
a.b = a;

Clone(a); // ❌ Fails with Maximum call stack error

This PR adds support for recursive structures by detecting and handling circular references. Objects that reference themselves (directly or indirectly) can now be processed safely without causing stack overflows.
