15/**
16 * A foreground service kept alive while an opencode agent is actively running. Holding a
17 * foreground priority lets the long-lived SSE `/event` subscription survive backgrounding
18 * (Doze/app-standby would otherwise choke the socket and stall streaming mid-run).
19 *
20 * The service is started when a run begins ([start]) and stopped when it goes idle
21 * ([stop]). It shows a low-importance "Agent is working…" notification in [NotificationChannels.STATUS].
22 * Started/stopped via Compose from the chat screen based on the `running` state.
