GitHub Copilot models seem to be hardcoded

[alessaba]

I noticed when using the VibeTunnel app that the copilot models don't update automatically when GitHub add them. The "copilot-api" project has automatic updating so it should definitely be possible. I don't have experience with Go, but i will try to see if i can solve the problem. In case anyone is more proficient, i'd appreciate it

I think the culprit function is:
func GetGitHubCopilotModels()

I confirm. Gemini 3 Flash was just released a few minutes ago in GH Copilot, and is still not available with CLIProxyAPIPlus.
