feat(models): Add GPT-5.1 model support (#367)

Added OpenAI's GPT-5.1 as the new flagship model for coding and agentic tasks with configurable reasoning effort. The model features a 400K token context window and 128K max output tokens, positioning it as the premier choice for complex development workflows. Updated all generated configuration files and adjusted model ordering to reflect GPT-5.1's priority placement.
