Adds a SubscribeStatus gRPC RPC that pushes a fresh FullStatus snapshot on every peer-recorder state change, replacing the Wails UI's 2-second Status poll. The daemon's notifier already triggers on Connected / Disconnected / Connecting / management or signal flip / address change / peers-list change; we now coalesce those into ticks on a buffered chan and stream the resulting snapshots over gRPC. - Status recorder gains SubscribeToStateChanges / UnsubscribeFromStateChanges + a non-blocking notifyStateChange that drops ticks when a subscriber's 1-slot buffer is full (next snapshot the consumer pulls already reflects everything). - Server.Status handler split: the snapshot composition is shared with the new SubscribeStatus stream handler so unary and stream paths return identical bytes. - UI peers service: pollLoop replaced by statusStreamLoop. The local name of the existing SubscribeEvents loop is now toastStreamLoop so the two streams are easy to tell apart — the underlying RPC name is unchanged. - Tray applyStatus skips the icon refresh when connected/lastStatus hasn't changed; rapid SubscribeStatus bursts during health probes no longer churn Shell_NotifyIcon or the log.
