Research direction

Start by reproducing the linked sphinx-graph workflow with Python 3.12 and Sphinx 7.2.6, then trace autodoc handling of the aliased type annotation in the class constructor. Done means the reference to rx.PyDiGraph resolves and the documentation build completes without the reported error.
