What this PR fixes

In exa_py/research/async_client.py, poll_until_finished uses asyncio.get_event_loop().time() to track elapsed time.

asyncio.get_event_loop() is deprecated since Python 3.10 when called inside a coroutine. Using it inside an async function emits a DeprecationWarning and may raise a RuntimeError in future Python versions.

The correct replacement when already inside a running async context is asyncio.get_running_loop().

Changes

• async_client.py: replaced 2 occurrences of asyncio.get_event_loop().time() with asyncio.get_running_loop().time() inside the poll_until_finished coroutine
