dsh-think-zh-expand-eac: A DSH Plugin to Force Chinese Thinking and Responses

The DSH plugin `dsh-think-zh-expand-eac` is an EAC-customized version of the original `dsh-think-zh-expand`, designed to resolve conflicts with collapsing plugins. It enforces the model to think in Simplified Chinese (while preserving code in its original form) through server-side system prompt injection, and uses `MutationObserver` to localize the interface on the client side. The plugin removes the functionality that takes over the renderer, returning thinking-block rendering to the host and enabling coexistence with `dsh-auto-collapse` or `dsh-turn-fold`. Installation requires Node.js >= 22 and depends on a specific version of cordis.
