dsh-board: Usage and Cost Panel for DeepSeek Harness Sidebar

dsh-board is a MIT-licensed open-source DeepSeek Harness (DSH) plugin maintained by dfkai, designed to address the fragmented usage, context, and cost tracking issues in Web GUI agents. The plugin integrates a sidebar panel in the bottom-left corner of the interface, providing cost estimates based on official pricing (including peak/off-peak rates), analysis of 1M context utilization, visual charts (such as token trends and daily heatmaps), and a "Word Merit" tier and achievement system. It supports light and dark themes, bilingual Chinese-English interface, and zero-decoration animations. All data is sourced directly from the local DSH public API without initiating any third-party requests. Users can install and enable it by running the `dsh plugin add` command followed by a process restart, or configure conditional toggles through configuration files. Note that the panel displays estimated values rather than billing proof, with actual charges subject to the platform's billing records.
