fix: create coroutine inside worker thread for asyncio.run

The coroutine was being created on the main thread before being passed
to ThreadPoolExecutor. This is incorrect as coroutines should be created
and run in the same thread. Use a lambda to defer coroutine creation
until execution inside the worker thread.
