ruff (v0.14.2) check TC003 for importing KW_ONLY in python 3.13.

Auto (unsafe) fix result:

from __future__ import annotations
from dataclasses import dataclass
from typing import TYPE_CHECKING
from dataclasses import KW_ONLY

KW_ONLY import in TYPE_CHECKING block cause TC004.

from __future__ import annotations

from dataclasses import dataclass
from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from dataclasses import KW_ONLY


@dataclass
class DataClass:
    a: int
    _: KW_ONLY
    b: int

Interesting, thanks for the report and for finding the other issue! It seems like I probably missed something here when adding the future-annotations setting.
