feat: register vm_start, vm_stop, and vm_restart in kubevirt toolset

Update the kubevirt toolset to include the new VM lifecycle management
tools. This commit:

- Adds imports for vm_start, vm_stop, and vm_restart packages
- Registers all three tools in the kubevirt toolset's GetTools() method
- Updates test snapshot data to reflect the new tools

These tools provide complete VM lifecycle management capabilities
through the MCP server, allowing AI assistants to start, stop, and
restart KubeVirt VirtualMachines.

Code was assisted by Cursor AI
