feat(playback): Implement detailed view for showChat

- Integrate the rich formatting logic into the 'showChat' function.
- When 'playback' is called with a UUID, it now prints a full,
  detailed transcript of that specific chat topic, including
  content from external files, tool calls, and code snippets.
