Fix Agentic cross-hardware engine selection

[adibarra]

Summary

• scope Agentic STP engine exclusions to each hardware SKU
• allow configurations such as B200 SGLang and MI355X vLLM on the same chart
• preserve same-SKU engine conflicts and global MTP comparability restrictions
• propagate exclusion scope through official/overlay selection handling

Verification

• resolver smoke: cross-hardware selection allowed; same-hardware conflict blocked
• pnpm --filter @semianalysisai/inferencex-app test:unit -- src/lib/exclusion.test.ts src/components/inference/utils/comparison-exclusion.test.ts (2,610 tests passed)
• pnpm --filter @semianalysisai/inferencex-app exec cypress run --component --spec cypress/component/scatter-graph.cy.tsx (16 tests passed)
• pnpm typecheck
• changed-file oxfmt --check

Note

Medium Risk
Changes core legend/GPU selection and comparability logic for Agentic charts; mistakes could show incomparable engines together or block valid comparisons, but behavior is heavily unit- and component-tested.

Overview
Agentic Traces STP engine rules no longer treat different GPUs as one global engine pick. Exclusion specs gain optional scope: 'hardware' and compiled rules expose scopesOf, so cross-engine STP is blocked only on the same SKU (e.g. B200 SGLang vs B200 vLLM) while mixes like B200 SGLang and MI355X vLLM can stay on one chart. Global MTP cross-engine limits are unchanged.

The exclusion resolver (pickStickyGroup, toggles, legend universe) resolves conflicts per scope, correlates global MTP with hardware STP when picking a sticky engine, and reports partial families when one engine remains on another GPU. effectiveLegendItems accepts a remembered multi-GPU selection so solo/restore-all does not drop idle SKUs or forget each hardware’s engine.

InferenceContext passes scopesOf for official/overlay keys, keeps preferredHwTypesRef for legend toggles, and surfaces conflict toasts when resolution is partial. Toast copy distinguishes partial vs whole-family drops.

Tests cover resolver behavior, comparison-exclusion matrix, toast messaging, and Cypress scatter/table scenarios aligned with hardware-scoped STP.
