Addition of an enhanced coding mode ---->

[emperormaestro]

In high yielding agents, the agents use two models one for reasoning and another one while coding like claude code or augment code.
But in roo code, in the code mode, there is option for selection of only one model.

For users to get an experience close to the one mentioned above, they have to toggle modes. Introduce a feature that allows the user to choose if they want to add a separate model for the reasoning or planning in the code mode or in roo code general settings(like a check box which would be optional ; if checked then user has to add a separate model for reasoning or planning.also keep in mind they the user should be able to use a different api from a different provider ; for example, reasoning with api key from openai using gpt-5 and coding with api key from anthropic using claude 4.5 sonnet and ). This would make the agent more powerful and also give less hassle to developers.
