dsh-workbuddy-connect-functy: Dashboard and Multi-Account Rotation

`dsh-workbuddy-connect-functy` is a feature-enhanced branch of `dsh-workbuddy-connect`, intended to integrate the WorkBuddy desktop app's models uniformly into DeepSeek Harness (DSH) through a dashboard, multi-account rotation, and quota display. The plugin supports adding multiple accounts via QR code or token, automatically handles rate-limit retries, and provides domestic enterprise billing interfaces. Installation requires logging in to WorkBuddy first and compatibility with specific DSH versions. To use it, simply select it in the model selector; it supports image input and inference tier detection. Note that the international version may face deactivation risks and relies on the WorkBuddy client API.
