dsh-conversation-folding: DSH Conversation Flow Rendering Enhancement Plugin

`dsh-conversation-folding` is a DSH UI enhancement plugin developed by TheHeartFickle, designed to address the issue of overly long conversation flows. It optimizes presentation through a folding mechanism, with core features including: collapsing entire rounds of thinking and tool calls by default; grouped folding of Tool call steps; and enhanced scrolling display for Think blocks. Users can customize folding toggles for different step types in settings. Plugin configuration is persisted on the browser side without affecting underlying logic, making it suitable for developers who want to reduce excessive scrolling and focus on reading the main content.
