fix: correct coroutine_wrapper target in wrap_AsyncBackgroundExecutor_submit (closes #1739)

[botbikamordehai2-sketch]

What

In wrap_AsyncBackgroundExecutor_submit, coroutine_wrapper was incorrectly called with wrapped (the AsyncBackgroundExecutor.submit method itself) instead of func (the coroutine function being submitted). This caused the wrong object to be wrapped and passed as the callable to submit, breaking LangGraph's weakref.WeakMethod usage in the runner.

Fix

Change func = coroutine_wrapper(wrapped, context) to func = coroutine_wrapper(func, context) so the submitted coroutine function is wrapped with the transaction context, not the submit method itself.

Closes #1739

Good catch, that was definitely a typo. Thanks for the quick fix. We'll try to get this released early next week with some other things.
