/// #712: The Claude Code path in the real sandbox, with a stand-in for <c>claude</c> —
/// the real one does not run on the test machine, and a test has no key. The stand-in
/// checks what Claude Code would be given (arguments, key, home, MCP configuration),
/// reaches the API host through the proxy, calls the MCP server the way Claude Code
/// would (the command from mcp.json) and answers in stream-json.
