Window Stats: Cross-session Statistics Plugin for DeepSeek Harness Web

wellorbetter/dsh-plugin-window-stats is a local, read-only, MIT-licensed plugin for DSH Web, designed to address the lack of a global observation panel when running multiple sessions in parallel. The plugin requires no external network requests and does not write session data, providing a full-window overview, session analysis, and a right-side drawer view. Core features include real-time monitoring of session progress and token usage, as well as cost estimation based on DeepSeek's official pricing (distinguishing between V4-Flash/Pro and cache hit status), supporting currency switching between USD, CNY, and others. Additionally, the plugin offers token trend charts, tool execution time distribution, heatmaps, and summaries for each round of tasks, while continuously displaying the running count and total consumption at the bottom of the sidebar. Installation is simple via the `dsh plugin` command.
