Hi! I’ve implemented the Open vSwitch support requested in #79.

I followed the existing systemd-networkd pattern to keep the integration consistent with the project’s current structure.

Summary:

• Added config-examples/openvswitch/setup.sh.
• Automated bridge/port management via ovs-vsctl.
• Kept the standard key generation flow.

Attached a quick demo of the script execution. Let me know if you need any changes.
