	The Python special-method ("dunder") name for a member operator, or nullptr if welder does not expose that operator.

Detailed Description

The C++-operator → Python special-method ("dunder") map shared by welder's Python backends.

pybind11 and nanobind expose the same Python object model, so a member operator maps to the same dunder in both (operator+ → __add__, …). This header holds that one map so neither backend re-derives it — the Python analogue of <welder/rods/lua/metamethods.hpp> and <welder/rods/python/doc_style.hpp>. A backend calls welder::rods::python::operator_dunder from its special_method_name (the map that both gates operator eligibility and names the slot) and its add_operator.

Requires the welder vocabulary first (#include <welder/vocabulary.hpp>), like the rest of the reflection layer.
