Description
Make sure that the driver supports GIL disabled correctly handling mutable objects. Read https://docs.rs/pyo3/0.28.2/pyo3/pycell/struct.PyRefMut.html. Possibly introduce requirement for every class to be frozen and manage mutability through Arc and Mutex with *_py_attached lock extenstion traits #64.
With this in mind we should reduce holding inside structs other user-exposed structs and .clone() usage.
Consider forbidding #[derive(Clone)] to make handling more explicit. Especially with Mutex interior mutability.

Research direction
Start by reading the linked PyO3 0.28.2 PyRefMut documentation and the context of issue #64. Audit how user-exposed structs handle mutable state, cloning, and Mutex interior mutability under GIL-disabled Python. Done means the project has a decided, consistently applied approach for free-threaded support, with affected behavior validated.
