YueGuobin 7a2d15cb64 feat: clarify default LLM model config selection logic
Updated documentation and implementation to clearly define the priority order for selecting default LLM model configurations. The logic now explicitly states:
1. User's config marked with `is_default: true` (highest priority)
2. Group's config marked with `is_default: true`
3. First config in the list (user configs come before group configs)

This ensures consistent behavior between the API documentation and the actual implementation in the repository code.
