DeepSeek Harness Plugin: dsh-usage-mini

dsh-usage-mini is a lightweight floating dashboard plugin designed for the DeepSeek Harness Web client. It aims to address the pain point of users frequently switching pages to check subscription quotas and API spending by displaying key data on one side of the screen to improve efficiency. Core features include monitoring the balance, usage, and countdown timers for Claude/Codex subscriptions and the DeepSeek API, as well as supporting UI language synchronization, window drag position memory, and automatically stopping polling when collapsed to conserve resources. The plugin depends on the `dsh-plugin-subscriptions` and `dsh-cost-meter` plugins, supports Web mode only, and does not persist sensitive data, providing users with a low-interference monitoring solution.
