Description
When the parent asyncio task calling query() is cancelled (e.g., user presses Stop, or cleanup calls task.cancel() + await task), the anyio cancel scope inside the SDK raises:
RuntimeError: Attempted to exit cancel scope in a different task than it was entered in

RuntimeError: Attempted to exit cancel scope in a different task than it was entered in
Reproduction
- Start a
query() call inside an asyncio.create_task()
- From a different context, cancel that task:
task.cancel(); await task
- The SDK's
query.close() → self._tg.__aexit__() raises the RuntimeError
Expected behavior
Cancellation should propagate cleanly without RuntimeError. The cancel scope should detect cross-task cancellation and handle it gracefully.
