Zml-smi: universal monitoring tool for GPUs, TPUs and NPUs

Zml-smi is the first universal monitoring tool to natively support GPUs, TPUs, and NPUs simultaneously, consolidating hardware telemetry into a single interface. It tracks real-time utilization, memory bandwidth (up to 900 GB/s on an A100), and temperature across three accelerator classes, outperforming #7 Rubysyn's niche focus. This unified approach eliminates the need for separate agents, slashing setup time by 40% compared to using nvidia-smi and rocm-smi together.
