dsh-notify Plugin: Desktop and Remote Browser Notifications

dsh-notify is a plugin for DeepSeek Harness (DSH) designed to address the issue of delayed monitoring of agent task status. It provides desktop toast notifications and remote browser push alerts, supporting real-time reminders when a task is completed, encounters an error, or awaits user intervention. The plugin supports command-based control, a global toggle, and session filtering. It relies on Windows and WinRT to implement desktop notifications and is compatible with DSH version 0.1.7.
