Add comprehensive doc comments to BatchEnqueueContext, the Broker interface method, and the RDB implementation explaining that the batch uses a Redis pipeline (not MULTI/EXEC), so partial success is possible and individual Lua scripts are atomic but the batch is not. Fix a bug where Script.Run inside a pipeline only sends EVALSHA without the automatic EVAL fallback that non-pipeline calls get. On a fresh Redis (or after SCRIPT FLUSH), this caused NOSCRIPT errors for every pipeline-batched script invocation. The fix preloads the required Lua scripts before building the pipeline. Also roll back the in-memory queuesPublished cache when the pipeline fails, preventing stale entries from suppressing future SADD calls.
