In the system prompt, the <claude_background_info> section says:

The most recent frontier Claude model is Claude Sonnet 4.5 (model ID: 'claude-sonnet-4-5-20250929')

But the default model is now Opus 4.5 (claude-opus-4-5-20251101), which is newer.

Suggest updating the background info section in the system prompt.

Verified on 2.0.57.
