Get Tool Output From ToolkitTask

Is your feature request related to a problem? Please describe.
There is no easy way to get Tool outputs in ToolkitTask. The output of the Task is always the LLM's textual response.

Describe the solution you'd like
Be able to access Tool outputs from ToolkitTask instead of (in addition to?) the LLM's final interpretation of it.

Describe alternatives you've considered

• Using ToolTask. This Task lacks the CoT of ToolkitTask and only supports a single Tool.
• Accessing ToolkitTask.subtasks. Maybe a variation of this could work. That way we're not making any assumptions about which Tool call the user wants.
