* Added an option for tool selection configurations, i.e.:

`Would you like to inform the Tool Selection Agent of each tool's requirements? Doing so could improve the selection outcome, but it will consume more tokens and processing power.`

* optimised tool `recommend_tool`

* get rid of old tool selection code to make launching faster

* testing gui in developer mode
