felixxia-oai b473c4e6ab Record Guardian v2 classification token usage (#39303) ...

## What changed

- Pass session-attributed extension metrics to the Guardian v2 sampler.
- Record `codex.guardian_v2.classification.token_usage` histograms for total, input, cached input, cache-write input, non-cached input, output, and reasoning output tokens.
- Preserve token accounting when streamed JSON produces an early score by recording usage from the terminal response in the background.

## Testing

- Cover token metrics through the Guardian v2 extension and the sampler's early-score path.
