Function deepCloneInstance

Deeply clones a class instance, preserving its prototype, inherited properties, and special object types like Map, Set, Date, and RegExp. Also handles cyclic references.

Features:

• Retains the entire prototype chain, ensuring methods like toString() work as expected.
• Recursively clones objects, including nested structures.
• Supports special objects (Date, RegExp, Map, Set).
• Handles cyclic references to prevent infinite loops.
• Supports a custom _clone(seen) method if defined on the object. This allows classes to override the default cloning behavior and perform specialized cloning while still participating in cycle handling.

Limitations:

• WeakMap & WeakSet: Cannot be cloned because their entries are weakly held.
• Functions & Closures: Functions are copied by reference; closures are not recreated.
• DOM Elements & Buffers: Not supported, as they require specialized handling.
