[FEATURE] Add tools for computer use

[edenreich]

Summary

Currently this CLI only support non-gui applications.
The goal of computer use is to actually let the AI reason about denoised and compressed screenshots, click things, open apps, type etc.

In a GUI world it's getting more expensive so it's important to ensure a compression and denoising is done properly to avoid excessive usage of tokens.

For the first version it's supports only Linux Ubuntu. Windows or Mac-OS is out of scope (future versions).

Acceptance Criteria

• There is a tool set of computer use as a separate config section.
• Computer use is disabled by default.
• The web terminal streaming the UI of the remote machine in a window - similar to how vnc works.
• It's documented.
• It's tested.
