+- 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.
