Subject: [PATCH 1/2] Accept both text_completion and chat.completion in
 completions response

The OpenRouter API returns object: "chat.completion" for the /completions
endpoint, but the SDK was only accepting "text_completion". This caused
validation errors when using the completions.generate() method.

This change updates the CompletionResponse type and Zod schema to accept
either value, since the API behavior may vary or change.

Also added an E2E test to verify completions work correctly.

Fixes #101

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The TypeScript SDK repo does not accept direct changes to generated code.
Only the OpenAPI spec change and E2E test should be included.
The maintainers will regenerate the SDK after merging.
