 * Detects runs of 3+ consecutive calls to the same tool, analyzes

 * - A batch tool call (if the tool accepts arrays)
 * - A cycle/hook pattern (if iteration must happen in the graph)
 *
 * This function is entirely tool-agnostic -- it knows nothing about
 * playwright, screenshots, or any specific MCP server.
