fix(openai.ts): default to an empty string if undefined

Change:



const urlHost = new URL(this.options.openAiBaseUrl).host;



To:



const urlHost = new URL(this.options.openAiBaseUrl ?? "").host;



because the nullish coalescing operator (??) to default to an empty string if this.options.openAiBaseUrl is undefined.



It ensures that the URL constructor always receives a valid string.
