Some providers (e.g. codebuddy/cbcn) attach an empty tool_calls array to every streaming chunk. An empty array is truthy in JS, so the guard 'if (delta.tool_calls)' closed the message on the first content token and emitted response.output_text.done early, dropping the remaining deltas. Guard on a non-empty array; finish_reason still closes the message and real tool calls still close it before emitting function_call items. fixes #3234

- CORS OPTIONS: 200 response, empty body, correct headers
- Authentication: missing key, bad format, old-format key, wrong key value, valid key
- Body validation: invalid JSON, missing model, missing input, bad model
- Happy path: single string, array, correct delegation, CORS header, machineId override
- Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
- Error propagation: non-fallback errors passed through, 429 exhausts accounts
- machineId override: validates key, rejects wrong key
