dsh-token-live: DeepSeek Harness Live Statistics and Cost Comparison Plugin

`dsh-token-live` is a browser-side plugin for DeepSeek Harness (DSH), developed by `woodfood111`. It injects hooks to read internal state and adds a statistics panel below the conversation editor, addressing the limitations of native features in real-time statistics and cost comparison. Core features include CJK-weighted draft counting, session consumption calculation based on the official pricing table, context usage display, and cross-model cost comparison. It does not require API keys, and its security is ensured by the browser sandbox. The installation command is `dsh plugin --profile web add dsh-token-live`.
