/**
* Integration Tests: CLI Wizard Tool Fetching
*
* Tests the fix for empty wrapper generation bug (#71).
* Verifies that wizard fetches real tools from MCP servers before generating wrappers.
*
* NOTE: These are placeholder tests documenting the expected behavior.
* Full integration testing requires actual MCP servers running, which is beyond
* the scope of unit tests. Manual testing should verify:
* 1. Wizard connects to MCP servers during wrapper generation
* 2. Real tool schemas are fetched via client.listTools()
* 3. Wrappers contain actual tool functions (not empty skeletons)
* 4. Client connections are properly cleaned up (client.close())
