Token Costs Danger: Make auto-mode switching conditional on a per-mode basis

[ScyDev]

I'm using these SPARC .roomodes: https://github.com/ruvnet/rUv-dev/blob/main/.roomodes
Running the SPARC Orchestrator with Google Gemini 2.5 Pro and the Coder with Claude 3.7 Sonnet.

Sometimes the Orchestrator decides to just switch mode, instead of creating a subtask. If it does this with a substantial accumulated Gemini context, it fills up Claude immediately, causing huge costs and a chat that won't be much use.

Therefore, it would be great if auto-mode switching could be allowed only for specific modes: if I could prevent Orchestrator (or any other mode using Gemini with big context) from spontaneously switching mode. But still allow auto-mode switching for other modes.
