dsh-ui-billing: Sidebar Billing Plugin for the DeepSeek Harness Web Interface

The DeepSeek Harness Billing Plugin is a client-side component that displays the current session cost and real-time API balance at the bottom of the sidebar in the web interface. Maintained by HenryHwong, it calculates the CNY cost of the current conversation, refreshes the account balance every 60 seconds, displays the ¥ symbol when the sidebar is collapsed, and runs in an idle state by default to conserve resources. It must be installed via the DSH Plugin Manager and supports custom pricing tables and timezone configuration. The plugin is read-only, secure, and requires no additional API calls, making it suitable for developers who need fine-grained control over API costs.
