This PR introduces a new inactivity package responsible for monitoring peer activity and notifying when peers become inactive. Introduces a new Signal message type to close the peer connection after the idle timeout is reached. Periodically checks the last activity of registered peers via a Bind interface. Notifies via a channel when peers exceed a configurable inactivity threshold. Default settings DefaultInactivityThreshold is set to 15 minutes, with a minimum allowed threshold of 1 minute. Limitations This inactivity check does not support kernel WireGuard integration. In kernel–user space communication, the user space side will always be responsible for closing the connection.
