/**
* Issue #2905 — custom models (added via the UI) on opencode-go / openai-compatible
* nodes always routed as OpenAI-compatible because there was no way to set a
* per-model `targetFormat`. `addCustomModel` didn't accept it, the API schema
* stripped it, and routing (`getModelTargetFormat`, static-registry-only) never
* saw it — so a custom model that needs the Anthropic Messages shape fell back
* to the provider default ("openai").
*
* This test verifies the persistence + getModelInfo-injection chain: a custom
* model saved with targetFormat: "claude" is surfaced on the resolved modelInfo
* (which chatCore then uses before the provider default).
