Introduction to the DSH Auto-Collapse Dialogue Node Plugin

`@ycp424c/dsh-auto-fold-turn` is an external plugin for DeepSeek Harness (DSH) designed to address the problem of excessive process nodes in long conversations. Through DSH's Conversation Node extension interface, it automatically folds tool calls, intermediate messages, and similar items in a conversation turn into summary lines without modifying core code. Users can click to expand or collapse them, and the state persists via localStorage. The plugin uses a fail-open strategy to ensure that native content is fully displayed when exceptions occur.
