Protect real-time subscriptions

Protect publishes real-time updates over WebSocket at /v1/subscribe/devices and /v1/subscribe/events. The SDK dials these reusing the same auth and TLS as REST.

c := unifi.Local(host, apiKey, unifi.WithInsecureSkipVerify())

stream, err := c.Subscribe(ctx, unifi.AppProtect, "/v1/subscribe/events")
if err != nil { /* ... */ }
defer stream.Close()

for frame := range stream.Frames() {
    // Use any event type from the generated lib/protect/<version> package.
    // CameraMotionEvent is one concrete example; choose the type that matches
    // the event payload your application handles.
    evt, err := unifi.Decode[protectv7_1_46.CameraMotionEvent](frame)
    if err != nil { continue }
    // handle evt
}

The decode type comes from whichever lib/protect/<version> package you choose, so the same WebSocket layer serves every coexisting version.
