Add MCP client loading and printing functionality
- Introduced a new `printMCPs` function to display loaded MCP clients, categorizing them into standard and agent clients for better clarity. - Enhanced the `Load` function to include loading MCP clients from the assistants directory, improving the overall MCP management. - Added tests for loading assistant MCPs, ensuring that the functionality works as expected and that agent clients are correctly identified and logged. - Updated model loading to support agent models from assistants, ensuring proper integration and functionality across the system.
