* Run a single read tool to completion and return its raw ToolResult, * classifying expected failures the same way execute's catch does so * the SHAPE is identical whether dispatch runs in-process or on a worker: * NotIndexed → success-shaped guidance, PathRefusal → clean er

(toolName: string, args: Record<string, unknown>)

   * path validation already ran in {@link execute} before routing here.
