/**
* Go Adapter Smoke Tests via MCP Interface
*
* Tests core Go debugging functionality through MCP tools
* This test would have caught missing integration points (adapter registration, etc.)
*
* Validates actual behavior including:
* - Adapter can be loaded through AdapterLoader
* - Session can be created with language: 'go'
* - Breakpoints work with Delve
* - Stack traces and variables are accessible
* - Go-specific features (goroutines, etc.)
