 * @fileoverview Tool for visual identification via a single model call.

 * The semantic browser agent uses this tool when it needs to identify
 * elements by visual attributes not present in the accessibility tree
 * (e.g., color, layout, precise coordinates).
 *
 * Unlike the semantic agent which works with the accessibility tree,
 * this tool sends a screenshot to a computer-use model for visual analysis.
 * It returns the model's analysis (coordinates, element descriptions) back
 * to the browser agent, which retains full control of subsequent actions.
