/**
 * #3227 / #3233 — combo names broke on /v1/responses in v3.8.9+.
 *
 * The Codex CLI WS→HTTP fallback added `resolveResponsesApiModel`, which rewrites a bare
 * model id to `codex/<id>` whenever `codex/<id>` resolves to the codex provider. Codex
 * accepts ANY model string, so a *combo* name with no slash (e.g. `n8n-text`,
 * `paid-premium`) was force-rewritten to `codex/<combo>` and sent to Codex —
 * "No credentials for provider: codex" / "model not supported" — instead of being
 * resolved as a combo. The fix skips the codex rewrite when the bare name is a combo.
