feat: enhance reasoning replay functionality and integrate call recording

- Added a new test to validate the projection of reasoning response items to valid input items in the Codex API.
- Introduced `CallRecorder` to track network requests and responses during plugin interactions.
- Updated the `PluginRegistry` and `PluginWorker` to support call recording, ensuring that reasoning items are correctly processed and recorded.
- Refactored the `responses_input` function to handle reasoning items more effectively, improving the overall response handling logic.
