[FEATURE]: Support GitHub Copilot Raptor mini (Preview)

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

I would like OpenCode to support GitHub Copilot Raptor mini (Preview) as an available model when using GitHub Copilot as the provider.

Currently, Raptor mini (Preview) does not appear in the model list, although it is available within GitHub Copilot. This model is lightweight while offering better accuracy than GPT-5 mini, making it a strong option for tasks that require a balance between performance and quality.

Adding support would expand model selection options and help OpenCode stay aligned with the latest models provided by GitHub Copilot.

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: Cannot use new models from github copilot #13864: Similar feature request for supporting new/missing GitHub Copilot models
• openai codex 5.3 not showing in models list through github copilot #13742: Missing model in the GitHub Copilot model list (same symptom — model available in Copilot but not appearing in OpenCode)

If your request is already covered by one of those, consider adding a comment there instead.

We are not allowed to support it, github copilot team explicitly asked us to remove.
