test: add comprehensive tests for isRecommendedAgentModel function

Added tests for Gemini 3 Pro model recognition and other agent models.
Tests cover:
- OpenAI o1/o3/o4 models
- DeepSeek R1/Reasoner models
- Gemini 2.5 and 3.x Pro models (including new gemini-3-pro-preview)
- Claude Sonnet 3.7+ and Opus 4 models
- xAI Grok Code models
- Case insensitivity and edge cases
