DSH Usage Panel: DeepSeek Harness Consumption Statistics Plugin

dsh-usage-panel is an MIT-licensed plugin designed specifically for the DeepSeek Harness (DSH) web profile, aimed at addressing the challenge of scattered and difficult-to-monitor token usage in multi-model, multi-provider environments. The plugin provides a visual "Usage Statistics" panel on the settings page, with core features including displaying cumulative total usage, cache hit rate, the proportion of the most frequently used models, and an activity heatmap for the past six months. It supports toggling daily token trends at the model level across time periods (7/14/30 days) and lists the Top 10 high-consumption sessions to distinguish between primary sessions and sub-agents. Additionally, the plugin displays token distribution across providers and models, and supports exporting complete JSON data as well as data compliant with the RFC 4180 standard.
