• cf63828: fix(google): read serviceTier from usageMetadata.serviceTier in both generate and stream paths

  The previous implementation read serviceTier from the x-gemini-service-tier
  response header, which is only populated on non-streaming responses. Gemini
  streaming includes the value in usageMetadata.serviceTier on every chunk, so
  providerMetadata.google.serviceTier was always null for streams. Read from
  usageMetadata for both paths instead.
