Add VS Code detection and MCP registration to install/uninstall

The install command detected many editors (Cursor, Zed, Gemini, etc.)
but not VS Code, even though cbm_install_vscode_mcp() already existed.
Add VS Code User config dir detection and wire it into both install
and uninstall flows, writing to ~/.config/Code/User/mcp.json (Linux)
or ~/Library/Application Support/Code/User/mcp.json (macOS).
