Capture and replay SSE streaming responses with a completeness gate, tagging cache entries with their body format (json/sse) sourced from the ai-providers streaming framing. Also refactor Redis connection management into a shared with_redis helper with fail-open handling, and improve error handling in the L1 backfill path.
