vkg-oai 3f4668da20 Add history-aware prewarming for idle threads (#48812) ...

## What changed

- Add `CodexThread::prewarm_with_history()` to prepare a WebSocket response with existing conversation history and executed-tool metadata using `generate: false`. The next turn can reuse the prepared response when its prompt extends that history and request settings match.
- Keep startup prewarming and `prewarm()` on the existing empty-input path, and skip preparation when the cached WebSocket is ready.
- Label prewarm telemetry by input mode and WebSocket continuation metrics with `after_prewarm`.
- Rename `persistent_mode_enabled` to `persistent_execution_enabled` without changing its behavior.

## Testing

Extend WebSocket coverage to check history preservation during reconnect prewarming, reuse of the prepared response on the next turn, and omission of `previous_response_id` for a non-prefix prompt.
