[Feature Request] Auto-detect advisor model from session when explicitly enabled

Bug Description
If advisor is enabled explicitly, don't require specific model to use for advisor. Instead, be able to detect curren't agent's session model and automatically choose the next better model.
Issue: I use the always latest opus model version. And I carry over the years ago settings.json with the advisor model fixed to opus. The agent won't call to advisor because the specified in settings is not explicitly upper model than the running session/context one
