dsh-axia-cachebilling: Real-time Token Billing and Cache Monitoring in the DSH Context Overlay

dsh-axia-cachebilling (XiaBilling) is a web plugin specifically designed for DeepSeek Harness (DSH) to address the high cost of caching and the lack of real-time data in long sessions. It seamlessly integrates billing and monitoring capabilities into DSH's native popup without requiring additional pages. Core features include three-tier billing statistics, eight context metrics derived from real logs, token statistics, and automatic multi-currency conversion with peak/off-peak pricing support. The plugin includes a built-in pricing catalog for mainstream models, supports one-click price entry, and provides flexible configuration options. Users can install it by running a command; after a restart, they can view real-time costs and detailed statistics in the context usage popup.
