fix(cloud): correct Cerebras model + use .chat() for /v1/chat/completions compat

- Model: llama-3.3-70b → gpt-oss-120b (correct Cerebras fast-inference model)
- Use cerebras.chat(model) instead of cerebras(model) — AI SDK v4 defaults to
  /v1/responses (OpenAI Responses API) which Cerebras doesn't support; .chat()
  forces /v1/chat/completions
- Refactor useProvisioningChat to direct fetch() instead of shared client
  import, avoiding cross-package dep that broke the build
