nit: Add return type annotation. Also, I'd suggest adding a docstring indicating that this returns a single global AsyncioExecutor instance.

We can make the types here more precise by using ParamSpec:
from typing_extensions import ParamSpec
...
P = ParamSpec("P")
...
def submit(self, func: Callable[P, Awaitable[R]], *args: P.args, **kwargs: P.kwargs) -> duet.AwaitableFuture[R]:
...| import duet | ||

| _R = TypeVar('_R') |

nit: I'd probably suggest using R here instead of _R, since it's more common. Not actually sure why we used underscore prefixes on type variables in engine_client.py.
| future = asyncio.run_coroutine_threadsafe(func(*args, **kw), self.loop) | ||
| return duet.AwaitableFuture.wrap(future) | ||

In preparation for the streaming client prototyped in #6145, AsyncioExecutor is pulled into a separate file so that it's accessible from
stream_manager.py, a dedicated file forStreamManager.@maffoo @wcourtney
