WeakMap.prototype.delete() — has() after delete

📖 Usage Example

const wm = new WeakMap()
const k = {}
wm.set(k, 1)
wm.delete(k)
wm.has(k)  // → false

After delete(), has() confirms the key is gone.

WeakMap delete() and has()

After delete, has(key) returns false.

Challenge: Verify has() reflects deletion.
