#### Free-Threaded Python Support (Python 3.13t)
Python 3.13 introduced an experimental free-threaded build (also known as "nogil" or ABI tagged as ``3.13t``)
where the Global Interpreter Lock (GIL) can be disabled using the ``Py_GIL_DISABLED`` flag. This enables
true parallelism for Python threads on multi-core systems.
where the Global Interpreter Lock (GIL) is disabled (indicated by the ``Py_GIL_DISABLED`` compile-time macro).

For safe multi-threaded use:
- Create a separate ``Z3_context`` (``Context()`` in Python) for each thread
- Do not share Z3 objects (contexts, solvers, formulas, etc.) between threads
- Use the ``.translate(ctx)`` method to move objects between contexts when needed
- Use the ``.translate(ctx)`` method to copy objects to a different context when needed
2. **Safe Pattern Example**:
