Bump pyo3 0.24 -> 0.29 so symclaw-python builds on Python 3.14

The bindings could not build against the installed interpreter, so the
whole workspace had to be checked with --exclude symclaw-python. Two API
changes: PyObject left the prelude (now Py<PyAny>), and #[pyclass] types
implementing Clone must opt in to the FromPyObject derive.
