Enum .name property has str type

Bug Report
I stumbled across a weird issue with literals and using the .name property with enums. I was wondering if this is expected behavior. Seems inconsistent to me.

To Reproduce

from enum import Enum
from typing import Literal


class Foo(Enum):
    A = 1
    B = 1


keys = Literal["A", "B", "C"]


def f(name: keys) -> None:
    print(name)


foo: Foo = Foo.A

f(foo.name) # Error: Argument 1 to "f" has incompatible type "str"; expected "Literal['A', 'B', 'C']"
f(Foo.A.name) # No Error

Expected Behavior

I would expect both versions to be valid.

Your Environment

• Mypy version used: mypy 1.15.0 (compiled: yes)
• Mypy command-line flags: none
• Mypy configuration options from mypy.ini (and other config files): none
• Python version used: 3.11.11

まず、mypy 1.15.0 で issue の最小限の Python 3.11 再現コードを実行し、foo.name と Foo.A.name の推論された型を比較します。これらの式に関係する enum と Literal の処理を追跡し、その後、報告された呼び出しのカバレッジを追加して、動作が合意された期待値と一致することを確認します。
