feat(kubevirt): add vm_guest_info tool for QEMU guest agent access

Add new vm_guest_info tool that enables querying information from inside
VirtualMachines using the QEMU guest agent, without requiring SSH access
or credentials.

The tool supports querying:
- os: Operating system information (name, version, kernel, hostname)
- filesystem: Mounted filesystems and disk usage
- network: Network interfaces and IP addresses
- users: Currently logged-in users and sessions

This provides a secure way to gather runtime information from VMs for
monitoring, troubleshooting, and compliance purposes.
