feat: update CLI model lists with latest OpenAI, Anthropic, and Google models

- Add GPT-5, GPT-5 mini, GPT-5 nano, GPT-4.1, and o3-mini for OpenAI
- Add Claude 3.7 Sonnet, Claude 4 Sonnet, and Claude 4.1 Opus for Anthropic
- Add Gemini 2.5 Pro, 2.5 Flash, and 2.5 Flash-Lite for Google
- Add comprehensive tests for updated model constants
