redis-py raises redis.exceptions.TimeoutError when a blocking XREADGROUP
returns no data within block_ms. On idle streams (US market closed → no
market:bars / signals:generated / trades:executed) every blocking read
times out; the unhandled exception tore down each worker's asyncio.TaskGroup
and exited the process, putting signal-generator, trade-executor and
learning-engine into CrashLoopBackOff. Catch it and keep polling.
