dsh-native-notifications: System-level notifications for DSH approvals, questions, and task completion

This article introduces `dsh-native-notifications`, a DSH client plugin maintained by `tommy00748-tech`. It monitors events such as `agent/status`, `approval/request`, `user-questions/request`, `agent/error`, and `sign-in`. System desktop notifications are triggered by the DSH page itself and are attributed by the operating system to "DeepSeek Harness"; clicking the banner returns to the session. Non-responsive approvals do not trigger false positives, errors do not cause repeated alerts, and long-running multi-agent tasks only trigger a single alert. The ringtone is synthesized using Web Audio, allowing users to select presets or customize up to eight notes in Settings → General. The article provides official installation commands from the README, configuration file snippets, common configuration options, audit log locations and troubleshooting paths, the working principles of the Host/Client halves, as well as information on compatibility, applicable scenarios, and a reminder to check the source code before installation.
