feat: agent Request JSON format + ask tool for asking the task dispatcher for the details

[pkarw]

Related to #60
Would be great to have a constant format of the agent request message - which consists of all the details required for this task to be executed by the agent (e.g. results of the previous tasks, some overall goal information, etc.); to let us keep agents separated but communicated. The constant format is maybe not a bad idea as it will let us easier build a debugging tools.

Then there should be a tool to ask for the details - that seems required to perform the task but was missing in this request. It works like @grabbou described in the #60 - so kind of short-term memory based on the overall message context.

Isn't this duplicate of #5? :D

@grabbou no, #5 was about agents asking other agents- this one was about the Request format plus asking Disparcher which is different kind of animal 🦒😁
