Implement a hook useObject(initialObject) that provides a reactive object with utility functions.

The hook should:

• Accept an optional initial object to populate the state.
• Provide methods to get, set, delete keys.
• Provide a method clear() to remove all keys.
• Provide a method keys(), values(), entries() to access the current state.
• Updates to the object should be reflected immediately through these methods.

Example

const obj = useObject({ a: 1, b: 2 });
obj.set("c", 3);
obj.get("a"); // 1
obj.delete("b");
obj.has("b"); // false
