on_tool_start should return tool name

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

At the moment, the on_tool_start event only returns the class name not the actual name.

I am reusing tool classes and the actual tool name is not available in the stream.

Motivation

I want to return the tool name to the end user. Ideally with the actual name. I have solved it like this:

class Tool extends StructuredTool {
  get lc_id() {
    return [...this.lc_namespace, this.name];
  }
}

Proposal (If applicable)
