`NamedTuple`'s `_tuplegetter` is not recognized

mypy parses NamedTuple class definition in the same way it parses regular class variables:

from typing import NamedTuple
from typing import reveal_type


class A(NamedTuple):
    foo: str = "foo"


reveal_type(A.foo)
a = "_" + A.foo

mypy t.py

t.py:9: note: Revealed type is "builtins.str"
Success: no issues found in 1 source file

python3 t.py

Runtime type is '_tuplegetter'
Traceback (most recent call last):
  File "D:\workspace\client\t.py", line 10, in <module>
    a = "_" + A.foo
        ~~~~^~~~~~~
TypeError: can only concatenate str (not "collections._tuplegetter") to str

mypy --version && python3 --version

mypy 1.16.1 (compiled: yes)
Python 3.13.5

Start by reproducing the reported NamedTuple example with mypy 1.16.1 and Python 3.13.5, then trace how the NamedTuple class definition and A.foo are analyzed. The issue is done when mypy recognizes the runtime _tuplegetter behavior and reports the mismatch or otherwise prevents the unsound concatenation.
