+Fix silent multi-minute hangs in the OpenAI/Codex reviewer path
+
+- Configure the OpenAI client with `timeout: 120s, maxRetries: 0` so the SDK's defaults (600s timeout + 2 silent internal retries) can no longer stretch one hung request into 30 minutes of unlogged silence.
+- Classify abort/connection failures (no HTTP status) as retryable — the SDK's `APIUserAbortError`/`APIConnectionError` keep `name: 'Error'`, so the old `name === 'AbortError'` check never retried them.
+- Race the stateless (ChatGPT backend) stream against the 120s abort and abort the SDK stream controller in `finally`, as a backstop for mid-SSE stalls.
+- Bound the Codex OAuth token refresh fetch with a 30s timeout — it runs outside the review AbortController and could hang the whole review silently.
+- Log before each API call and tool execution, and log the previously-silent tool-loop continue paths (cache hit / repeat limit / budget block), so a stall now names its await.
