DSH Plugin dsh-fold: Collapsing Consecutive Tool Calls and Long Inputs

The dsh-fold plugin is designed to optimize the interaction experience of the DeepSeek Harness Web GUI. Built on native Slot and React technologies, it collapses consecutive tool calls within the same turn into a single line, while displaying runtime status and call counts in real time. The plugin also limits the display of excessively long user inputs by automatically collapsing content that exceeds three lines, while ensuring diagnostic information is never collapsed. Additionally, it supports automatically loading older history. The plugin depends on DSH version 0.1.5 or 0.1.6, handles only turn-level logic, and does not rely on DOM manipulation.
