Return a response for a tool invocation that started from an AI Tool node.

## Where to Find It

## What It Does

The Tool Response node sends the tool result back to the original AI Generate request so the model can continue with the returned data.

## Configuration

1. **Name** (optional) - Provide a friendly label for the node.
2. **Output** (required) - The property containing the tool result.
   * Use a `msg` reference (default: `msg.payload`) to return a computed result.
   * Use a static string when you want to return a fixed response.

## Outputs

* Strings are returned directly.
* Objects are stringified before being returned to the model.

Use this node at the end of a tool execution path so the model receives the tool output.
