Background
Fix to #12771
Previously, the gateway backend returned usage in AISDK's v2 shape, including inputTokens and outputTokens as numbers, regardless of the spec version. Because the AISDK gateway v3 emits specificationVersion: "v3", the process to convert v2 usage to v3 usage never happened, so result.usage remained undefined.
Summary
In /gateway, I added normalizeGatewayUsageToV3() to convert v2 usage results to v3 usage results before returning them. I used existing tests that assert that usage is normalized to v3 shape to verify that my solution works.
Manual Verification
I used generateText() on a local example and confirmed that result.usage has numeric values filled out, instead of being undefined.
