DSH Side Chat: Open a Parallel Side Conversation alongside the Main Dialogue

DSH Side Chat is an MIT-licensed plugin designed for DSH, aiming to address the issues of overly long and cluttered main conversation contexts. The plugin provides parallel side conversations with independent context windows, enabling context isolation and preventing temporary tasks from polluting the main conversation. Core features include truly parallel agent sessions, side panel management (supporting multi-session switching), Markdown rendering, panel width adjustment (300-900px), and minimized background operation. Users can use the "bring back to main conversation" feature to have the side agent automatically summarize and inject a collapsed summary into the main session, keeping the main conversation flow clean. The plugin supports two installation methods: a dynamic Cordis plugin mode suitable for debugging and an npm package mode suitable for daily use. Typical usage involves creating side conversations via the panel or the `/side` command, with each main session
