* perf: cut per-instance CPU cost of shared socket.io Redis pub/sub channel Profiling a multi-instance deployment (py-spy --gil) showed ~44% of worker CPU in the socket.io pub/sub listener. Two causes, two fixes: - Add hiredis so redis-py parses the RESP protocol in C instead of pure Python (redis/_parsers/resp3.py alone accounted for ~28% of GIL samples; redis-py auto-selects the hiredis parser when importable). - Subclass AsyncRedisManager to drop emits whose target room has no local participants before upstream _handle_emit re-encodes the full packet. Every instance receives every emit published on the shared channel, so with N instances all but the hosting one were paying full packet re-serialization per message just to deliver it to nobody. Broadcasts (room=None) are unaffected.

Open WebUI only ever emits to scalar string rooms or room=None, so the case is unreachable today; guard on isinstance(room, str) anyway so any non-string room shape passes through to upstream behavior unchanged. Every open-webui emit uses a string room, so the fast path still covers all real traffic.
