Tools could be more encapsulated

[trashhalo]

I started planning out an implementation to add ripgrep as an AI tool to let the agent search your codebase.

I noticed tools are kind of a leaky abstraction. They kind of have an interface defined but the tool manager is stacks of case statements with deep knowledge of how each tool works.

If you plan on adding more tools you might have a better time by defining a contract for what a tool can do and remove all knowledge of tools from tool manager other than a list of tools and the plugs for the interface.
