Implement robust system for re-routing requests to run in terminal that should go to a different tool

[Tyriar]

We have these currently:

• Alternative recommendations that route run in terminal tool requests to python/jupyter extensions https://github.com/microsoft/vscode-copilot-chat/blob/dd244c66bcbea2b334be1dfc5d931c42ae257854/src/extension/tools/node/runInTerminalTool.tsx#L268
• Command re-writing when we can remove redundancies in the command to simplify chat and the resulting command https://github.com/microsoft/vscode-copilot-chat/blob/dd244c66bcbea2b334be1dfc5d931c42ae257854/src/extension/tools/node/runInTerminalTool.tsx#L293

We should have a general mechanism for re-routing requests to more "native" tools. For example a simple mkdir call should prefer the CreateDirectoryTool.
