DeepSeek Harness: Enhanced Session Quota Monitoring

`lstalu/dsh-quota-meter-plus` is an enhanced quota monitoring plugin for DeepSeek Harness (DSH). It provides accurate token billing, real-time progress bars, peak and off-peak pricing, and weekend discounts, while supporting independent per-session accounting and automatically blocking calls that exceed the budget. Users can view their balance and usage via Capsules, and API keys are securely stored. After installation, refresh the client to activate the changes; the Host-side process must be restarted. When upgrading, pay attention to the price list override logic and same-origin protection rules.
