dsh-offpeak-saver: DeepSeek Harness Off-Peak Cost-Saving Scheduler

**dsh-offpeak-saver** is a local workflow plugin for DeepSeek Harness, designed to defer non-urgent tasks to idle periods through a scheduling mechanism, thereby reducing peak-hour operating costs and improving resource utilization. The plugin provides features such as automatic queuing, estimated execution time display, streaming responses, a local SQLite-based persistent queue, sidebar dashboard monitoring, and tool calling support. Developers can submit tasks via conversational commands, Prompt markers, or tool calls, and manage priorities through the dashboard. The plugin requires DeepSeek Harness 0.1.0-rc.6 and a Node.js 22.19+ environment, and currently supports off-peak execution and cost control.
