 * #7364: "zai"/"glm-coding-apikey" default to the Anthropic Messages wire format
 * (registry format:"claude"), but a per-model `targetFormat` override (custom-model
 * dropdown, #2905) can resolve to "openai" — e.g. for a vision model like glm-4.6v
 * that the operator wants routed through the OpenAI-compatible endpoint instead.
 * chatCore/executionCredentials.ts threads that resolved override onto
 * `providerSpecificData.targetFormat`; DefaultExecutor.buildUrl() has no other way
 * to see it, so without this check every zai/glm-coding-apikey request silently hit
 * the Claude-format endpoint regardless of the override.
