dsh-balance-chart: Balance and Spending Visualization Plugin for DSH Web GUI

dsh-balance-chart is a zero-dependency Web GUI plugin for DeepSeek Harness (DSH), designed to eliminate the need for users to frequently switch pages when checking their balance, consumption, and billing periods. It renders a dual-layer chart in the session title bar to display real-time balance progress, peak and off-peak periods, per-turn consumption, and daily cumulative usage. It supports collapsing, hover-to-view details, full-screen invoice viewing, and customizable settings. Installation requires cloning the repository and configuring cordis.patch.yml; once installed, it enables intuitive monitoring of account status directly in the browser.
