Add KraftKit Support for Hyperlight

This project adds Hyperlight as a new VMM backend in KraftKit, enabling Unikraft unikernels to run with `kraft run --plat hyperlight`. The work will introduce platform registration and a new Hyperlight driver in the machine layer, then implement the full machine lifecycle: create, start, stop, delete, inspect, list, logs, and watch. It will start with a minimal boot path for a basic kernel, then extend to networking and storage support where possible. By the end of the project, KraftKit will have first-class Hyperlight support, and users will be able to manage Hyperlight machines through the standard CLI workflow.
