* fix: improve handling of ToolCallingAgent output in ToolCallingAgentComponent

The code changes in `ToolCallingAgent.py` modify the `ToolCallingAgentComponent` class to improve the handling of the output from the `ToolCallingAgent`. The changes include updating the logic to handle both single results and lists of results, extracting the relevant text from the results, and assigning it to the `result_string` variable. This ensures that the `result_string` contains the appropriate output to be returned as a `Message` object.

* fix(ToolCallingAgent.py): fix variable name typo from 'result' to 'results' for correct data processing
