di ci: glm-5-2 1p 1d && 2p1d

[JiaoliangYu]

Motivation

Add a GLM-5.2-FP8 ATOM DI CI case for TP-only 1P1D validation.

Technical Details

• Add GLM-5.2-FP8 to models_atomesh.yaml.
• Configure the model to use ${ATOMESH_MODEL_ROOT}/GLM-5.2-FP8/.
• Run ATOM backend with FP8 KV cache.
• Use 1P1D multi-node topology with one prefill TP8 worker and one decode TP8 worker.
• Add benchmark concurrency levels: 128, 256.
• Enable full GSM8K evaluation with few-shot 3.
• Run GSM8K eval at concurrency 64 and 256.
• Add a manual workflow dispatch switch: run_glm_5_2_fp8.
