Pipeline and caller-supplied MPUs keep topology on the MPU object, not the legacy groups globals. Logging those globals made PP/TP runs look like DP=world and TP=1. Signed-off-by: YeonwooSung <neos960518@gmail.com>

What
Record static ZeRO, precision, and DP/TP/PP/SP topology on enabled monitor backends when the engine finishes initializing.
Fixes #7494
Why
WandbMonitoronly calledwandb.init()and never wrote run config. The engine already logs per-step scalars (lr,loss_scale, timings), but users could not see ZeRO stage, offload devices, or parallelism sizes on the W&B/Comet/TensorBoard run.Changes
collect_monitor_config()builds a JSON-safe snapshot (stage, offload, precision, batch sizes, DP/TP/PP/SP rank and world size)MonitorMaster.update_config()fans out on rank 0wandb.config.update(..., allow_val_change=True)experiment.log_parameters(...)add_text("DeepSpeed/config", ...)deepspeed_config.csv__init__when monitoring is enableddocs/_tutorials/monitor.mdwas missing commas between backend objects; that is fixed hereThis PR does not add new engine rank getters; those are a separate follow-up to #7423.
