SimpleChatTC: ToolCalling enabled, Sliding window adjust

Chances are for ai models which dont support tool calling, things
will be such that the tool calls meta data shared will be silently
ignored without much issue.

So enabling tool calling feature by default, so that in case one
is using a ai model with tool calling the feature is readily
available for use.

Revert SlidingWindow ChatHistory in Context from last 10 to last 5
(2 more then origianl, given more context support in todays models)
by default, given that now tool handshakes go through the tools
related side channel in the http handshake and arent morphed into
normal user-assistant channel of the handshake.

 #### ToDo
 
 Is the tool call promise land trap deep enough, need to think through and explore around this once later.
