    Summary: `IterMut` violates Stacked Borrows by invalidating internal pointer

    Details: Affected versions of this crate contain a soundness issue in the `IterMut` iterator implementation. The `IterMut::next` and `IterMut::next_back` methods temporarily create an exclusive reference to the key when dereferencing the internal node pointer. This invalidates the shared pointer held by the internal `HashMap`, violating Stacked Borrows rules.
