Describe the feature or problem you'd like to solve
Background agents in GitHub Copilot Desktop currently run using an automatically selected model, and users cannot override or choose a different one.
Proposed solution
Add model-selection control to the desktop app’s settings in a dedicated background agents tab in to assign models to each background agent. This would bring the desktop app to parity with VSCode, where the Explore Agent's model can be set by going to GitHub › Copilot › Chat › Explore Agent: Model
Example prompts or workflows
No response
Additional context
This request is related to Issue #4178, which focuses on showing the effective model used by background agents.
