### Problem Statement Make a separate integration for `concurrent.futures`, handle scope forks correctly ### Solution Brainstorm see https://github.com/getsentry/sentry-python/issues/4508#issuecomment-3003526348 [this test](https://github.com/getsentry/sentry-python/blob/5709b25e817b9c64d729254de53d9ffd96a187ec/tests/integrations/threading/test_threading.py#L87-L91) captures a bit of the behavior but will fail with thread re-use so also write better tests
