Function _resolve_python

eval/run_compare.py:208–233

Interpreter for ``pip``/``-m swebench``/``uvicorn`` subprocesses. When ``SWEBENCH_PYTHON`` (or the given *env_var*) is unset, we use :data:`sys.executable` — the same Python that is running *this* script — so a venv-local ``uv pip install -e ./SWE-bench-dev`` is visible to ``prepare``.
