Fix ZEUS2 Grafana link routing by detecting run_name pattern

[aas008]

Problem

ZEUS2 runs store accelerator='H200' in the CSV but use H200-zeus2- prefix in run names. The existing code matches on accelerator == 'H200' before checking the H200_ZEUS2 mapping, routing ZEUS2 runs to H200_NEW/H200_OLD dashboards instead of the correct ZEUS2 dashboard.

Solution

Add _is_zeus2_run() helper function that checks for H200-ZEUS2- or H200_ZEUS2- prefix in run names, and check this pattern before the generic H200 accelerator check. This matches the existing pattern for HERA and HERA2 clusters.

Testing

ZEUS2 runs with H200-zeus2- prefix in run_name will now route to:

• vLLM: d35f19c8f56250/vllm-2b-dcgm-metrics-psap-zeus-syd
• SGLang: sglang-dcgm-metrics-psap-rhaiis-h200 (shared H200 dashboard)

Summary by CodeRabbit

• New Features
  • Added support for detecting H200 ZEUS2 runs.
  • Metrics links for these runs now route to the appropriate Grafana dashboard.

📝 Walkthrough

Walkthrough

The dashboard detects H200 ZEUS2 runs with hyphenated or underscored prefixes and routes their Grafana links to the H200_ZEUS2 configuration before generic H200 routing.

Layer / File(s)	Summary
ZEUS2 detection and Grafana routing dashboard.py	Adds _is_zeus2_run for supported run prefixes. ZEUS2 runs now use the H200_ZEUS2 Grafana dashboard configuration before date-based H200 routing.
