fix(inference): block cross-engine AgentX STP comparisons / 阻止 AgentX STP 跨引擎对比

[adibarra]

Note

Medium Risk
Touches core inference comparison UX (legend, overlays, presets, URL restore) and new sequence-scoped rules; mistakes could hide valid configs or allow misleading cross-engine charts, but behavior is heavily tested.

Overview
Agentic Traces now enforces a sequence-scoped STP rule: unsuffixed standard-token configs from different engine families (e.g. SGLang/ATOM vs vLLM) cannot share one comparison view. Fixed-sequence STP is unchanged. The rule merges with existing DeepSeek V4 MTP exclusions; MTP strip prefixes also cover llm-d and Mooncake wrappers.

Inference selection is centralized via resolveComparisonSelection / toggleComparisonSelection: legend toggles, GPU timeline picks, URL/preset restores, and unofficial overlay keys (overlay: namespace) all go through the same resolver. Agentic views use a keep-sticky policy (one engine family kept on auto-reset); other scenarios keep clear-all. The MTP-specific toast is replaced by EngineComparisonConflictToast with blocked vs resolved messaging (EN/ZH).

Chart surfaces apply the guard in ScatterGraph (drops conflicting overlay rooflines and syncs overlay state) and ChartDisplay (table rows and CSV warning inputs use visibleComparisonRows with quick filters). Preset hw matching ignores only non-null exclusion suffixes. Unit and Cypress tests cover STP grouping, overlay/table behavior, and regression cases.
