Allow setting custom temperature per mode

[codingelves]

For instance, Architect temperature=1 and Code temperature=0.3 (since for the Architect it's better to have some "creativity" while the Code agent should stick to the instructions).
It would be even better if the Orchestrator could set an agent temperature when switching roles.

Already doable via different profiles. Not entirely sure if low/high temp will affect coding output directly, but I'm not THAT deep in LLM.
