Copilot CLI model availability mismatch with web

### Describe the bug

I’m a GitHub Copilot Pro individual user.
In GitHub web Copilot, I can select Claude and Gemini models.
But in Copilot CLI, /model only shows GPT models (no Claude/Gemini).

Environment:
- OS: macOS (Darwin)
- Copilot CLI version: [paste output of /version]
- Account type: Copilot Pro (individual)

What I tried:
- /update
- restart CLI
- /logout then /login
- /model (still no Claude/Gemini)

Expected:
CLI should offer the same model family availability as web (or clearly explain why not).

Please help check whether this is a rollout/entitlement issue on CLI side.
