- Implemented a new SPA page for LLM Bridge and MCP Server settings in `llm-config.js`. - Added functionality for managing LLM and MCP configurations, including toggling, saving settings, and testing connections. - Created HTTP endpoints in `llm_utils.py` for handling LLM chat, status checks, and MCP server configuration. - Integrated model fetching from LaRuche and Ollama backends. - Enhanced error handling and logging for better debugging and user feedback.
