I've decided against making one giant composable for the Tool and Widget components. I think it's an unnecessary abstraction to deal with for now if the only goal is code deduplication. Maybe we can revisit it once we've added more tools, as reducing the bundle size may become a driving reason. My primary goal is to ensure readability of the tool logic while keeping flexibility.

Good cleanup. Small bug then good by me.
